Item PID and Novel Approach of PI Fuzzy Logic Controllers for Active Surge in Centrifugal Compressor(Springer, 2013) Chetate, Boukhmis; Zamoum, R.; Fegriche, A.; Boummdine, Mohand SaidThe operating range of aerodynamic compressors is usually limited by a phenomenon known as surge. Active surge control has showed the ability to extend the operating range significantly. This study presents a solution to this problem based on classical PID regulator and a new PI fuzzy logic approach with three lines of protection. The fuzzy controller is designed to avoid the surge instability on a given compressormodel. Simulation studies showpromising results at different operating points compared to the results obtained using PID controllerItem Adaptive control of induction motor using artificial neural network with estimation of rotor flux(2007) Chetate, Boukhmis; Kabache, Nadir; Ladiguin, Anatoly NikolaevitchItem Influence of overvoltages in induction motors fed by PWM voltage inverters on power efficiency(IEEE, 2007) Chetate, Boukhmis; Belassel, M.T.Item A new and best approach for early detection of rotor and stator faults in induction motors coupled to variable loads(Higher Education Press, 2015) Allal, Abderrahim; Chetate, BoukhmisItem Artificial neural network control of the recycle compression system(2014) Zammoum Boushaki, Razika; Chetate, Boukhmis; Zamoum, Y.Item Minimum action time of a robust fuzzy speed controller for induction machine drive(Advances in Modelling and Analysis C, 2007) Chetate, Boukhmis; Bradai, RafikIn this paper, we propose a procedure to design an optimal fuzzy controller for indirect field oriented controlled induction machine drives. This controller has best possible performances with a minimum action time possible in a practical implementation. First, we design a fuzzy PI controller having the maximum of fuzzy sets (7 input/output membership functions), which show better static and dynamic performances. This controller is specific to speed close loop of an indirect field oriented induction machine drive. Then, in order to minimize its composition the ANFIS (Adaptive Network-Based Fuzzy Inference System) structure is applied to perform a structural and parametric optimization of this controller. We propose also, a procedure to reproduce the input/output mapping of this controller with an approximation using artificial neural networks (ANN)Item Extended-Kalman-filter based sensorless speed vector control of induction motor taking iron loss into account(Advances in Modelling and Analysis C, 2007) Chetate, Boukhmis; Kheldoum, A.In vector controlled induction motor drives, the instantaneous rotor speed is measured using whether sensors or estimators. Since the basic Kaiman filter is a state observer, its use in vector controlled schemes has received much attention. However, these schemes are based on the assumption that the existence of iron loss in an induction motor may be neglected. The paper shows the effect of iron loss on the extended Kaiman filter performance that is designed on the basis if the ironless induction machine model. Original simulation results are carried out to demonstrate this effect as well as the effectiveness of the suggested approach to minimise the speed estimation error without modifying the observer algorithmItem Fuzzy logic-based controller for position regulation of electric drives(Advances in Modelling and Analysis C, 2007) Chermalikh, A.V.; Chetate, Boukhmis; Maidanski, I.I.; Kheldoum, A.Electrical drives are characterized by their natural non- linearity owing to their proper design and their time-varying mathematical models. When used to drive industrial systems, e.g. variable speed or variable position drives, conventional control methods are usually applied to design speed and position controllers. However, at certain performance level, these methods are not satisfied. The present paper combines fuzzy logic, mostly used to control system characterized by non-linearity and uncertainty, with new control structures to overcome difficulties listed earlier. The obtained results have proved the good foundation of the suggested methodItem The use of root mean square values (RMS) for the shortcoming diagnostic of permanent magnet synchronous machine using artificial neurone network module(2008) Khodja, Djalal Eddine; Chetate, BoukhmisItem Compensation for the iron loss effect in EKF-based speed estimation of vector controlled induction motors(IEEE, 2008) Kheldoun, Aissa; Chetate, BoukhmisIn vector controlled induction motor drives, the instantaneous rotor speed is measured using whether sensors or estimators. Since the basic Kalman filter is a state observer, its use in vector controlled schemes has received much attention. However, these schemes are based on the assumption that the existence of iron loss in an induction motor may be neglected.
