Item Hybrid Backstepping Sliding Mode Controller for Stick–slip Vibrations Mitigation in Rotary Drilling Systems(Taylor et francis, 2021) Mendil, Chafiaa; Kidouche, M.; Doghmane, M. Z.The main objective of this paper is to suppress the stick–slip vibrations in the drilling system so that the drill bit can follow the desired nominal angular velocity of the Top Drive in an optimal time. Hence to protect drilling equipment from hazards and increase drilling performances by decreasing the non-productive time (NPT). Three control systems have been proposed to achieve this objective, a sliding controller is firstly designed and then a backstepping approach is discussed secondly. Furthermore, a hybridization of sliding mode control with a backstepping approach has been proposed on the so-called hybrid backstepping sliding mode controller. The latter has not been proposed before in the literature for rotary drilling systems. Moreover, two torsion models of the system have been discussed for different degrees of freedom. Based on the comparison between controllers’ responses, the effectiveness and the robustness of the hybrid controller have been demonstrated and highlighted, whose fast response can protect the drilling equipment from hazards that may be caused by the slip phase of the vibrations. Hence, it is recommended to implement the proposed controller in smart rotary drilling systems for petroleum industry.Item Decentralized overlapping control design with application to rotary drilling system(2021) Doghmane, Mohamed Zinelabidine; Kidouche, M.; Ahriche, A.The main objective of this paper is the development of overlapping decomposition strategy for con-troller design of rotary drilling systems based on the state feedback technique. The lamped modelof the system has been considered, Graph-based representation has been used to rearrange thestates of the model, and then a new model has been decomposed into subsystems after analyzingthe interconnection terms. The expansion–contraction principle, combined with Lyapunov theory,is used to investigate the global stability of the decomposed system so that controllability of thedesigned controller is guaranteed and its robustness is improved. Moreover, the designed strategyhas been validated with high-frequency mode stick-slip vibrations data measured in an operationalrotary drilling system of an exploration well drilled in an Algerian hydrocarbon fieldItem A New Decomposition Strategy Approach Applied for a Multi-Stage Printing System Control Optimization(IEEE, 2015) Doghmane, Mohamed Zinelabidine; Kidouche, M.; Habbi, H.; Bacetti, A.; Bellahcene, B.Large scale dynamic systems are one of the challenges facing control engineer today. The design of controllers is an intractable problem when applied to problems of high dimension with intricate structure. Many strategies have been recently developed to deal with decomposition of complex systems, these strategies are based on the idea of subdividing the whole system into smaller subsystems less difficult in study than the original one. The aim of our paper is to apply the approach of multi-overlapping control design to multistage printing systems controller. Our principle objective in this paper is to use the advantages of multi-overlapping decomposition technique and its application in order to have a more robust controller of multistage printing system. This approach leads to computationally efficient design strategies that are well suited for large scale applications. Multistage printing system model is presented to illustrate the effectiveness of the proposed algorithmItem Unknown Resistive Torque Estimation of a Rotary Drilling System Based on Kalman Filter(Taylor & Francis, 2020) Riane, Rami; Kidouche, M.; Illoul, R.; Doghmane, Mohamed ZinelabidineRotary drilling systems are widely used in petroleum engineering to drill oil and gas wells. Control of drilling process is a very important topic because it allows industrials to optimize drilling cost, improve borehole quality, and protect equipment. Many researchers have dealt with the control of rotary drilling systems, wherein, the main difficulty is that the rock-bit interaction term is highly nonlinear, and mathematical models simulate its dynamic but with insufficient fidelity because of the lack of measurement devices for bottom torque for these systems. In order to design an efficient controller, it is mandatory to have the model highly loyal to the rotary drilling system, which can represent the dynamic of the system under the rock-bit interaction term. The objective of this study is to estimate the unknown input torque based on Kalman filter, the estimation has been validated on a test bench. Moreover, it has been noticed that Kalman estimator has better efficiency in comparison to the pole placement method. The algorithm has been implemented on CompactRio using LabView environment and applied to experimental equivalent system to rotary drilling system equipmentItem Rt-lab and dspace : two softwares for real time control of induction motors(Editura Academiei Romane, 2014) Idir, A.; Kidouche, M.Item Stability of interconnected systems under structural perturbation : decomposition- aggregation approach(2008) Kidouche, M.; Habbi, H.; Zelmat, M.In this paper, the decomposition-aggregation method is used to carry out connective stability criteria for general linear composite system via aggregation. The large scale system is decomposed into a number of subsystems. By associating directed graphs with dynamic systems in an essential way, we define the relation between system structure and stability in the sense of Lyapunov. The stability criteria is then associated with the stability and system matrices of subsystems as well as those interconnected terms among subsystems using the concepts of vector differential inequalities and vector Lyapunov functions. Then, we show that the stability of each subsystem and stability of the aggregate model imply connective stability of the overall system. An example is reported, showing the efficiency of the proposed techniqueItem Real time rotor flux estimation for induction machine drives : an experimental approach(2010) Grouni, S.; Ibtiouen, R.; Kidouche, M.; Touhami, O.Item A perfectly symmetrical configuration in dual-bridge inverter topology for maximum mitigation of emi, common-mode voltages and common-mode currents(2010) Akroum, Hamza; Kidouche, M.; Grouni, S.; Zelmat, M.Item On lyapunov stability of interconnected nonlinear systems : recursive integration methodology(Springer Netherlands, 2010) Kidouche, M.; Habbi, H.This paper evolved from an endeavor to construct a Lyapunov function of interconnected nonlinear systems described by ordinary differential equations. This construction is an intractable problem and crucial part of the design when applied to problems of high dimension with intricate structure. The design obtained is applicable if the system under investigation is a generalization of the strict feedback form and whose dependency graphs satisfies the decomposition into lower triangular form. This design is mainly developed for moderated nonlinear continuous time dynamical systems. However, as we show in the example, it is emphasized that the present results can be extended to discontinuous systems provided they can be approximated by smooth modifications. A key step in our approach which based on back integrating procedure is to decompose the interconnected system into subsystems using graph theoretic decomposition. In the proposed methodology, the postulated Lyapunov function is obtained by backward integration the composite system trajectory. This novel approach leads straightforward and by one shot methods to both Lyapunov function of the composite system and its time derivative. A practical example is presented to illustrate the effectiveness of the resultsItem Novel loss optimization in induction machines with optimum rotor flux control(HyperSciences, 2010) Grouni, S.; Ibtiouen, R.; Kidouche, M.; Touhami, O.This paper focus on seeking optimum rotor flux which optimizes total energy control under practical constraints of currents, voltages and speed measurements. Improved flux optimization method is an important criteria to evaluate losses in indirect field oriented control for induction machine drives. The practical usefulness of our control models are evaluated and confirmed through experiments using an induction machine (1.5kW/380V). Simulation and experimental investigation tests are provided to evaluate the consistency and performance of the proposed control model
