Optimization of PI Parameter for Speed Controller of a Permanent Magnet Synchronous Motor

Abstract

This paper present the estimation of Proportional and Integral (PI) gain to control the speed of permanent magnet of synchronous motor. Modelling of a Permanent Magnet Synchronous Motor (PMSM) drive system and installation of PI controller in the Matlab Simulink also will discuss in this paper. The simulation includes all realistic components of the system and simulated in Matlab Simulink workspace based on the mathematical model of the system devices including permanent magnet synchronous motor and inverter. Detail implementation of permanent magnet synchronous motor and inverter also explained. Determination gain is adopted from Ziegler Nichols tuning method considering Proportional Integral (PI) in order to control the speed controller of a Permanent Magnet Synchronous Motor (PMSM). Analysis of the stability of speed rotation of PMSM by considering PI controller will discussed in this paper. Based on the obtain result, the performance of the stability of the permanent magnet synchronous motor considering PI controller are achieved.
