This paper describes the design and development of a novel controller for a non-linear power electronic converter. Neuro-Fuzzy controller is proposed to improve the performance of the buck &boost converters. The duty cycle of the buck & boost converters are controlled by NeuroFuzzy controller. The conventional PI controllers for such converters, designed under the worst case condition of maximu...

An adaptive fuzzy PID controller with gain scheduling is proposed in this paper. The structure of the proposed gain scheduled fuzzy PID (GS_FPID) controller consists of both fuzzy PI-like controller and fuzzy PD-like controller. Both of fuzzy PI-like and PD-like controllers are weighted through adaptive gain scheduling, which are also determined by fuzzy logic inference. A modified genetic algo...

In this paper we shows the experimental results using a microcontroller and hardware integration with the EMC2 software, using the Fuzzy Gain Scheduling PI Controller in a mechatronic prototype. The structure of the fuzzy 157 Research in Computing Science 116 (2016) pp. 157–169; rec. 2016-03-23; acc. 2016-05-11 controller is composed by two-inputs and two-outputs, is a TITO system. The error co...

Usage of flywheel energy storage system (FESS) is a common method for frequency regulation due to its high power injection capacity and long life time. FESS is equipped by two back-to-back inverters including grid-side inverter and machine-side inverter. In conventional method, the machine-side inverter sets the active power and machine flux while grid-side inverter sets the reactive power and ...

Power quality problem is t he most sensitive problem in the power system. The objective of the project is to reduce one of the power quality issue called “harmonics” using compensation technique. Shunt Active Power Filter (SAPF) is used to eliminate harmonic current and also it compensates reactive power. In this project, both PI controller and Fuzzy Logic Controller based three-phase shunt act...

This paper presents a novel speed control scheme of an induction motor (IM) using fuzzy-logic control. The fuzzy-logic controller (FLC) is based on the indirect vector control. The fuzzy-logic speed controller is employed in the outer loop. The complete vector control scheme of the IM drive incorporating the FLC is experimentally implemented using a digital signal processor board DS-1104 for th...

The development of high performance variable speed brushless dc motor drive is very important in all industrial applications. Generally, a high performance BLDC motor drive system must have good dynamic speed response, reference speed command tracking capability and load regulating response. Conventional controller such as PI, PID does not provide good dynamic response due to the problem of non...

Switched Reluctance Motors (SRMs) are increasingly popular machines in electrical drives, whose performances are directly related to their operating conditions. Their dynamic characteristics vary as conditions change. Recently, several methods of the modeling of the magnetic saturation of SRMs have been proposed as analytical functions. However, the SRM system is nonlinear and cannot be adequat...

A variable structure slip control strategy is developed for grasping objects by a robot end-effector. A hybrid controller comprised of a fuzzy controller and a PI controller is designed to perform the strategy. When a grasped object is slipped by an external force as a disturbance, the applied fingertip force is rapidly increased to stop sliding and then decreased to a reliable limit to hold th...
