The conventional speed controllers for vector controlled induction motor drive(VC1MD) suffer from the problem of stability, besides, these controllers show either steady state error (PD controller) or sluggish response (Pi, PID) to the perturbation in reference setting or during load perturbation. This paper presents a fuzzy logic based speed controller and its design for vector controlled indu...

A novel speed controller for the trapezoidal three–phase Brushless DC (BLDC) Motor Drive is proposed using a hybrid fuzzy logic/proportional plus integral (PI) control. The structure of the fuzzy logic controller is different from conventional fuzzy logic implementations such that it only uses three simple rules based on speed error being either in the positive, negative or zero regions. The co...

High Voltage Direct Current (HVDC) Transmission systems traditionally employ PI controllers with fixed proportional (P) and integral (I) gains Kp and Ki respectively. Although such controllers are robust and simple, they are not easily optimized to obtain the best performance under all conditions. In the field of intelligent control systems, fuzzy logic control and artificial neural network bas...

sliding mode control (smc) is a powerful approach to solve the tracking problem for   dynamical systems with uncertainties. however, the traditional smcs introduce actuator chattering phenomenon which performs a desirable behavior in many physical systems such as servo control and robotic systems, particularly, when the zero steady state error is required.  many methods have been proposed to el...

Proportional-Integral (PI) controllers are conventionally used in speed control applications of dc drives. These controllers provide good steady state response but do not provide better dynamic response during transient conditions. In this paper an effort is made to design a fuzzy logic controller (FLC), which can provide a better dynamic as well steady state response for speed control applicat...

This paper represents the design procedures of different compensation schemes for voltage mode controlled (VMC) dc–dc switching converters. Proportional integral derivative (PID) controllers, Fuzzy logic controllers (FLC), parallel combination of PID and FLC, and FLC tuned by PI controller have been investigated. MATLAB software is used to depict the buck converter performance with each compens...
