Abstract

This paper proposed on-line parameter estimation method to compensate the magnetic cross-saturation effect on the interior permanent magnet synchronous motor (IPMSM) control system for electric vehicle. The decoupling control model for IPMSM with magnetic saturation compensation based on SVPWM (Space Vector PWM) method is established. Though comparing the simulation results between model with saturation compensation of parameter estimation and ones without saturation compensation, it is verified that the control performance with saturation compensation is more stable and more accurate than that of without compensation over speed operating region especially at higher speed. The on-line parameter estimation method based on decoupling control improves the system following-up performance, robustness and the control accuracy effectively.

Summary

Introduction

IPMSM has become popular choices for high-performance traction applications used in production hybrid vehicles including the Toyota Prius, and Ford Escape. Since the effective air gap in the IPMSM is small and the effects of magnetic saturation and cross-saturation are EVS25 World Battery, Hybrid and Fuel Cell Electric Vehicle Symposium. The purpose is to present an improved current control method for IPMSM considering for magnetic saturation and cross-coupling based on decoupling control method by using SVPWM technology. Since the inductance is a function of d- and q-axes current that vary with operating conditions due to magnetic saturation, the compensated value of inductance is used in the control algorithm. Several models of IPMSM drives are set up by using different parameters including linear and nonlinear magnetic cross-saturation inductance parameters of the machine in flux-weakening control. Through the comparison of different models verify the excellent performance of the control system with decoupling control and compensation of magnetic saturation
