IPMSM Drive System Parameters Tuning - An Analytic Solution

Abstract

This paper describes an analytical way for tuning the parameters of vector controlled permanentmagnet synchronous machines. Current controllers are tuned to guarantee a 60° phase marginfor the identified parameters of the system. Gains of the controllers are modified to ensure amplitudemargin 2 of the current loop even for variable parameters of the machine. The velocity controller gainis tuned to maximize phase margin which is limited by a speed controller time constant placement.
