    Oven temperature control using siemens S7-1200 PLC
    (Université M'hamed Bougara Boumerdès: Institue de génie electronic et electric, 2024) Bendellali, Achraf; Kadri, Mehdi; Ouadi, Abderrahmane(supervisor)
    This report presents a comprehensive study on the design and implementation of a temperature control system for an oven using the Siemens S7-1200 Programmable Logic Controller (PLC) and a Human Machine Interface (HMI). It focuses on the PLC's programming environment, hardware configuration, and integration with the oven's sensors and actuators. The Hardware setup comprises the S7-1200 PLC, HMI, RTD sensor, measurement and control interfacing circuits, and heaters, which collectively enable data acquisition, signal processing, and actuation within the system. After acquiring oven data, identification of the system was performed using two different approaches, which are the Smith and Nishikawa methods. The PID control methodology employed in this study as extensive experiments and evaluations are conducted to analyze the performance of the developed control system. The system's response to various setpoint changes, disturbances, and load variations is tested experimentally to assess its stability, robustness, and accuracy in temperature regulation. The results obtained demonstrate the effectiveness of the proposed control system in maintaining the desired oven temperature within a tight range, even in the presence of external disturbances. The findings and insights obtained from this research provide valuable guidelines for designing and implementing control systems in similar industrial ovens (such as in: Pharmaceutical industry, Oil and Gas, Dairy industry … etc.).

    Modelling, controller design and implementation of a small-scale 3DOF helicopter using labVIEW and STM32F4xx microcontroller
    (Université M'hamed Bougara Boumerdès: Institue de génie electronic et electric, 2024) Debilou, Abdelalim; Manamani, Zineddine; Ouadi, Abderrahmane(supervisor)
    The 3DOF is a non-linear underactuated system. It is inspired from the Quanser 3DOF helicopter, however, the materials used and the dimensions as well as the motors are different therefore a model has to be define dan dimprove dfro mpreviou sworks . The 3DOF small-scale helicopter is a map of a real CHINOOK helicopter. The aim of this work is to create a platform for testing and deploying the different controllers as it will serve as an educational and research platform. Both linear and nonlinear system identification techniques were used to derive a model. The nonlinear model was linearized around the region of operation and then an LQR controller was designed. The redundancies such as the ADC for generating the control action were removed to reduce delay times and hardware costs.

Finally, a GUI for logging the data in order to evaluate the performance of the controlled process was designed.

    Automation and supervision of a top drive varco TDS 11/SA at entp (TP-232)
    (Université M'hamed Bougara Boumerdès: Institue de génie electronic et electric, 2024) Tifrani, Mohammed; Tiabine, Mohammed; Ouadi, Abderrahmane(supervisor)
    Oil and gas are regarded as key sources of energy in this century, and they are utilized in numerous nations worldwide. Our reliance on fossil fuels is so profound that oil companies around the world have decided to do their utmost to extract oil through a variety of drilling techniques to meet market demand. Companies have come up with a new drilling technology that involves introducing advanced equipment to accelerate the drilling process; this equipment is called the Top Drive. At ENTP, they use a legacy Control system based on old technology (Electro-hydraulic). It has a multitude of issues, notably when it comes to downtime because of the frequent, intensive maintenance needed; Therefore, in our study, we aim to renovate the control system of the Varco Top drive by introducing the torque and speed function, alarm function, brake function using a Programmable logical Controller with the human-machine interface which displays the speed, torque and set the torque limit with alarm, brake, and pipe handler screen to improve the control system and ease the supervision. The results of the experimental implementation demonstrate that a high level of automation can greatly improve equipment reliability and productivity.

    Design and implementation of an oven temperature controller using labview
    (Université M'hamed Bougara Boumerdès: Institue de génie electronic et electric, 2024) Elkarim, Fatiha; Adjeroun, El djawhar; Ouadi, Abderrahmane(supervisor)
    In this project, a closed loop temperature control system of an oven plant is designed and implemented including a digital computer, a data acquisition board together with a combination of hardware interfacing circuits and implementing a digital controlling algorithm. The temperature of the oven is measured using the RTD sensor and a signal conditioning circuit. This temperature feedback measurement from the plant is provided to the digital controller for calculating the required output to control the plant actuator (heating element). The temperature digital controller is requested to have the best performances in response to disturbances as step input temperature reference changes and also to step load changes. In the case of accurate oven temperature-controlled application, the performance of the controller does not tolerate output overshoot and a reduced settling time is needed for optimizing production and hence affects the oven property of production efficiency. Different tuning methods for the PID controller are explored, and their results are also presented. In addition to the PID controller, alternative control methods are proposed for improving the performance and reducing the overshoot in a first-order plus dead time temperature system. These alternative controllers include the Smith Predictor. This project provides valuable insights into the development and design of a feedback control system. The system ensures that the oven temperature remains stable at a predefined set point. It comprises a data acquisition unit that facilitates communication between the PC, the sensor conditioning circuit, and the power triac circuit, that control the amount of power delivered to the oven.

    Designing safety plc based gaz turbine protection system with integrated iiot solution
    (Université M'hamed Bougara Boumerdès: Institue de génie electronic et electric, 2024) Benabid, Asaad; Ouadi, Abderrahmane(supervisor)
    The project aims to design a gas turbine protection system to ensure safe and reliable operation. It addresses risks such as vibrations, high temperatures, and over speed, meeting SIL2 safety requirements. The core of the system is the Bently Nevada 3500, which collects real-time data on vibrations, temperature, and speed. A safety PLC, the S7-1500, analyzes this data to initiate timely actions for turbine protection. A user-friendly Human-Machine Interface (HMI) and Supervisory Control and Data Acquisition (SCADA) system, powered by the WinCC runtime, are implemented. This allows opera-tors to visualize real-time data and make informed decisions about turbine performance. Additionally, an Industrial Internet of Things (IIoT) solution powered by Node-RED is integrated. Two instances of Node-RED are employed: one as a central hub for efficient data collection, processing, and storage, and another hosted on a cloud-based server for remote access and advanced data management.The system incorporates automatic notification svi aemai lan dTelegra mi nth eeven to f aturbin etrip ,ensurin gswif tre-sponse and effectiv emitigatio nmeasures .B yintegratin gadvance dtechnologies ,thi sgas turbine protection system offer scomprehensiv emonitoring ,control ,an dsafet yfeatures.

    Virtual boiler simulation and control using lab VIEW
    (2017) Laraba, Yazid; Bendjabeur, Abdelhamid; Ouadi, Abderrahmane(supervisor)
    Worldwide, most electric power is produced by steam-electric power plants, which produce about 86% of all electric generation, enough reason to make it one of the most important challenges to nowadays engineers to develop more accurate models and virtual simulators, which is the main objective of our work. In this project, a boiler simulator is built based on physical (mass and energy) conservation laws, we first used MATLAB/SIMULINK to construct each subsystem model alone, and then the subsystems were integrated to get the full boiler system implemented. To enhance the performance of the boiler a Drum level control loop is implemented and simulated based on two main methods, one-element control and three element control. For interfacing we used LabVIEW to create a user accessible front panel, we then made use of the DAQ-USB6009 to communicate data between the boiler simulator and the control which was implemented in a different computer.
