The dynamic and static performance of the Shunt Active Filter depends strongly on adopted control methods. This paper deals with Virtual Flux Based Direct Power Control Methods for Shunt Active. Two commonly used VF-DPC algorithms (Fuzzy-DPC and classical DPC) are presented and discussed with respect to the resulting switching frequency, the harmonics compensation, the spectrum of the current s...

Real-time cell scheduling is a promising area for the application of evolvable hardware (EHW). In this paper, we describe an intrinsic evolvable and online adaptive EHW for solving the packet switching problem. Based on the coding and evolution scheme, we refer to it as evolvable fuzzy hardware (EFH), an extension of our proposed evolvable fuzzy system (EFS) [1, 2] and reconfigurable fuzzy infe...

This study proposes a combination of a fuzzy sliding mode controller (FSMC) with integral-proportion-Derivative switching surface based superconducting magnetic energy storage (SMES) and PID tuned by a multi-objective optimization algorithm to solve the load frequency control in power systems. The goal of design is to improve the dynamic response of power systems after load demand changes. In t...

This paper presents a hybrid form of control which has both Fuzzy Logic Control (FLC) and Variable Structure Control (VSC) integrated. This proposed Fuzzy Variable Structure Control (FVSC) approach combines the power of approximate reasoning of FLC with the switching synthesis used in VSC. The FVSC is applied to control and stabilize a micro satellite in space. A model of satellite is used in t...

Among all the drive control methods of induction motors, the Direct Torque Control (DTC) method operates independently of the rotor parameters of the machine and, despite its simplicity, provides good torque control in both stable and transient modes. The use of residual comparators in these drives reduces the torque ripple and variable switching frequency. The most common solution is the use o...

Abstract: A combination of Direct Torque Control (DTC) and Space Vector Modulation (SVM) for an Induction Motor (IM) drive is defined in this paper. A two-level SVPWM inverter is delivered to the induction motor drive. Using IM model in the stator D-Q axes reference frame. The inverter voltage is achieved based on inputoutput feedback linearization control. This paper signifies a Fuzzy Logic Co...
