Nonlinear Optimal Servo Control Design for PMSM with Inverter Voltage Norm Constraints

Abstract

In this paper, we consider the optimal servo design problems of the systems with input norm constraints. We propose a new method to design nonlinear optimal servo controllers satisfying the input norm constraints. This method is based on solving Hamilton-Jacobi equations via center-stable manifold theory. We verify the effectiveness of the proposed method by a computer simulation by using Permanent Magnet Synchronous Motor.
