Design and simulation of the control system for inverte-fed permanent magnet synchronous motor drive

Abstract

Development in the field of power electronics, cost effective DSP’s and microprocessors have opened a new era in the design and implementation of modern control strategies for variable speed drives. This paper presents the design of a control system which includes a non-linear controller and observer for inverter fed Permanent Magnet Synchronous Motor (PMSM) Drive. The entire design is carried out by designing of Speed Controller, Non-linear Controller (NLC), State Feedback Controller (SFC) and Non-linear Full order Observer (NFO). The proposed control scheme is extensively simulated under various conditions using MATLAB/Simulink, which shows better performance under all operating conditions for variable speed PMSM drive.
