Programmable Logic Controller (PLC)-based controller is one of the control device used in industrial automation drive applications, the important aspect is to control speed of an induction motor in the presence of variable load. The plant model in this project is developed using MATLAB/Simulink and the aim is to simulate and analyze the appropriate control technique suitable for implementation onto the PLC to perform real-time implementation of the VSD (variable speed drive) control. This paper presents the work conducted in analyzing, evaluating and improving a PLC-based intelligent controller for a Pulse Width Modulation Driven Variable Speed Drive (PWM Driven VSD) of an induction motor by using state space control method, focusing at the wide range of speed response. The results show that it is possible to archive a consistent control from low till high speed range. © 2011 IEEE. %Z cited By 1; Conference of 3rd National Postgraduate Conference - Energy and Sustainability: Exploring the Innovative Minds, NPC 2011 ; Conference Date: 19 September 2011 Through 20 September 2011; Conference Code:88531
