(Université M’Hamed BOUGARA de Boumerdes : Institut de génie electrique et electronique (IGEE), 2019) Zaoui, Sara; Boudia, Dounia Zed; Ouadi, A. (Supervisor)
Brushless DC (BLDC) motors are one of the most widely used electrical drive in industrial applications because of its performances; high efficiency, high torque than other motors. In this work, the permanent BLDC motor has been driven with the three arms inverter circuit (MOSFET) controlled using mainly rotor hall-effect position sensors. The analysis of the BLDC motor is simulated in open loop and closed loop design, including the loaded and loaded cases using MATLAB/ SIMULINK software. The conventional PI controller parameters are tuned using Ziegler-Nicholas method for the closed loop speed control of the BLDC motor. The dc voltage provided by the controller is used for adjusting the motor DC supply voltage by means of the duty cycle of the PWM circuit. This variable dc motor supply voltage causes the BLDC motor speed control. The Motor closed loop speed controller system is implemented using a PC based hardware and software interfaces. The hardware interface NI DAQ -6009 is used to read the motor actual speed and generating a variable dc voltage to control the PWM circuit. The software part which is a real-time LABVIEW program, aimed to implement the continuous PI controller and safety algorithms used for a correct system operation. For a deep study and tests of the behavior of the PI controller in loaded mode, a DC motor shaft is mechanically tied with the BLDC motor through a coupling mechanism. A PMBLDC motor rated at 24 Vdc, 1.56 A, 3000 rpm is used for the experimental tests. A Buhler PMDC motor is used rated at 24 Vdc, 2.5 A and 5000 rpm is used as load for the PM BLDC motor.

(2019) Sayeh Meddour, Yasser; Belghait, Naim; Ouadi, A. (Supervisor)
The scope of this project is to control the speed and the direction of dc motor using H-bridge and PWM and developing a mathematical model for the motor. It is asked to develop a 3-DOF (3 Degree Of Freedom) helicopter for laboratory experiment which is often used in control research education and analysis for the design and implementation of linear and non-linear control concepts. It is composed by three rotational joints, with the end bar carrying a pair of propellers actuated by DC motors. Measurements of the joints angles are supplied by incremental encoders. Two speed controllers based on Hbridges drivers for actuating the DC motor/propeller assemblies. Both angular measurements and control voltages provided by PC based hardware interfaces and software LABVIEW programs. Based on the identified model, a PID controller has been developed to control the speed of the motor. The simulation results show that the designed control system can guarantee high precision altitude and a good control under multi operation points

(2016) Mohammed, Abdelmalek; Ould Amara, Mouloud; Ouadi, A. (Supervisor)
This Project objective is to design and Implement a Programmable Logic Controller based automatic bottle filling using a Siemens SIMATIC S7-200 (CPU 226) PLC which acts as a field controller that runs the designed prototype by sensing the presence of bottle in a conveyor belt and then filling it accordingly up to a fixed level. In order to keep track of the overall process in real time, a four layers distributed Supervisory Control And Data Acquisition system was built to monitor and remotely control the bottle filling station over a local area network through an Human Machin Interface designed specifically for the proposed system that indicates the status of different process variables, displays alarms and log events. The SCADA system was deployed using LabVIEW software which makes the system cost efficient, flexible with an open environment and reliable solution for automation of small scale industries.

designed and implemented. The controller used is a Programmable Logic Controller (PLC) which reads all inputs provided by the system from the different sensors and call buttons inside and outside the cabin and produces accordingly output signals based on a program written in Functional Block Diagram (FBD) language, developed to control the different functionalities of the system. The four level controller is based on the first-come first-served basis, with the exception of priority cases, to reduce energy consumption. The PLC used is a Siemens S7-200 with 24 digital inputs, 16 digital outputs, and an analog input/output expansion module. A Variable Frequency Drive (VFD) is used to drive the AC Motor in both directions, forward and reverse, in a suitable speed to move the elevator cabin between floors in a smooth manner, Altivar 312 from Schneider Electric is the one used.
Modeling, simulation and control of quadruple tank process
(2019) Ould Amara, Massil; Bot, Mohammed; Ouadi, A. (Supervisor)
In control engineering, a single-input and single-output (SISO) system is considered as a simple system. However, numerous systems are not such uncomplicated, they have various data sources and returns. These systems are called multi-input and multi-output (MIMO) systems. Basic MIMO frameworks have some challenges since they are enormous and complex. Moreover, they have nonlinearities and loop interactions between their inputs and outputs. On the motivation behind considering multivariable systems, the quadruple tank process (QTP) is selected as a benchmark. This process is suitable for examining linear and nonlinear controllers and exhibits minimum and non-minimum system behaviour by essentially changing the setup of valve position. The PID and fuzzy Logic controllers of the nonlinear process (QTP) model is simulated in MATLAB/Simulink. The obtained results from simulation of the two controllers as well as system dynamic performances are discussed.

(2016) Bacha, Sofiene; Djebbari, Sidali; Ouadi, A. (Supervisor)
Gas turbines have become increasingly popular in the different power systems, due to their higher efficiency, especially when connected in a combined cycle setup. With increasing installations of gas turbines scheduled in different countries, the dynamics of the gas turbines become increasingly more important. The purpose of this work is understanding, modelling, and analyzing the behavior of 9FB General Electric gas turbine in the Combined Cycle Power Plant (CCPP) of Shariket Kahrabaa Hadjret Ennouss (SKH) with a view to investigate the power system problems. A description of the CCPP major parts is presented with specific description of the 9FB gas turbine and its combustion system. For modeling purpose, the parameters of Rowen’s model for the 9FB Heavy Duty Gas Turbine (HDGT) are derived and several simulated tests using Matlab/Simulink are executed. The way of obtaining the parameters are based on simple physical laws. It explains briefly how to extract the parameters of the model using the operational and performance data. Rowen’s model has provided a starting point for development of other models. Among these models, the Frequency Dependent model is taken to be under study since it is suitable for long-term simulation of power system dynamic performance involving abnormal frequency conditions.
PID Controller Tuning using DE and PSO optimization techniques
(2016) Alem, Mohamed Mounir.; Saidoun, Hakim; Ouadi, A. (Supervisor)
The PID controllers are the most popular and widely used controllers in industry because of their simplicity; robustness and successful practical application that can provide excellent control performance despite the varied dynamic characteristics of plant .Determination or tuning of the PID parameters continues to be important as these parameters have a great influence on the stability and performance of the control system. Most of the processes are complex and nonlinear in nature resulting into their poor performance when controlled by traditional methods. The need for improved performance of the process has led to the development of optimal controllers. In this project, two modern heuristic techniques which are particle swarm optimization (PSO) and Differential evolution algorithm (DE) are used for tuning and optimizing PID parameters. A classical method, which is Ziegler and Nichols method, is also used. Finally, a comparison is made between classical method (ZN) and optimization methods (PSO and DE) are applied on high order system, the proposed methods were indeed more efficient and robust in improving the control performances of the PID algorithm.
Upgrading of the zwick roell 1445 universal testing machine
(2022) Baali, Dhia Eddine; Brahimi, Abd Esselam; Ouadi, A. (Supervisor)
In mechanical tests, the main focus is to get a clear information about the tested material in order to avoid critical damages or to know characteristics of a new material. Accuracy, comfortability and reliability are relative features which can always be updated. In this project, a 1994 universal testing machine’s controlling system was migrated from solid- state microcomputer to Programmable Logical Controller (PLC), the old servo-motor was also replaced by a HSS86 closed loop hybrid servo-stepper motor. Using Siemens S7- 1200 PLC and LabVIEW a reliable, accurate, user-friendly and up-to-date supervisory software was created. The communication between the hardware and the software was via Ethernet, instead of the old serial communication, this was done using OPC server to create communication channel between the software and the machine. The developed software allows the user to test a material and to generate an Excel report.
