Designing of an effective and an efficient Fractional Order Proportional-Integral-Derivative (FOPID) controller, as a generalization of a conventional PID controller based on fractional order calculus, for an industrial control plant to obtain high-quality performances is of great theoretical and practical significance. This paper presents a new method for optimum tuning of practical FOPID controllers...
The direct torque control (DTC) suffers from high torque and flux ripples due to the use of hysteresis comparators. In this paper, an alternative method is presented for induction motor drive known by the model Predictive Torque Control (PTC). This technique includes the inverter model in control design and does not use any modulation block. The optimal selection of inverter switching states minimizes...
It is well known that the maximum likelihood (ML) algorithm is characterized by their complexity, which is very high. This paper presents a low-complexity semi-blind algorithm to jointly estimating the Carrier Frequency Offset (CFO) and channel based on oversampling in the receiving part for an Orthogonal Frequency Division Multiplexing (OFDM) system. The idea is to substitute the exponential term...
This paper presents a new and simple voltage control strategy for three phase current source inverter (CSI) using finite-set model predictive control. The proposed method can ensure an interruptible power supply (UPS) for the local loads of an islanded grid connected CSI independently of the type of these loads. The control of the inverter's output voltages is performed using the discrete model prediction...
