Juraj Aziza M. Zaki Osama Arafa Sanaa I.Amer Abeer H.Bashta

Mobile robotics is an area that deals with the control of autonomous and semiautonomous vehicles. The use of mobile robots is growing in a large number of applications especially in manufacturing, hazardous materials handling …etc In this paper, the navigation system built on a mobile robot operating in a warehouse is presented. As the mobile must be able to navigate from a known position to a desired new location and orientation avoiding any contact with fixed or moving objects while in Route, the sensory system is very important.

Maged N. F. Nashed Said Wahsh Hamed. G. Hamed Tarak Dakrory

This paper present application of electrical propulsion system of the Parallel Hybrid Electric Vehicle (PHEV) using three different Pulse width modulation (PWM) techniques and their results compared in terms of THD, DC voltage utilization, transient behavior, and the required execution time applied. The intelligent Fuzzy Logic Control (FLC) is applied to improve the dynamic performance of PHEV.

PI CONTROLLER BASED ON GENETIC ALGORITHM FOR PMSM DRIVE SYSTEM

Author: 
Faeka Khater Adel Shaltout Essam Hendawi Mohamed Abu El-sebah

This paper introduces a genetic-algorithm-based PI controller for position control of permanent magnet synchronous motor. The algorithm is proposed for optimizing the PI controller gains in the position control. Different controllers' strategies are applied for the cascaded-loop position controller, speed controller and current controllers. The controllers are compared together to select the best one. The objective target, which has been used for comparison, is the rise time, settling time, steady state error. In addition, the response of the developed torque is investigated.
