Abstract

Permanent magnet synchronous motor (PMSM) servo systems was widely used in industrial servos, automation, and other fields. With the advancement of industrial technology, high demands have been put forward for the response capability of PMSM servo systems. This paper addresses the issues of slow response speed and steady-state errors that traditional servo motor position closed-loop control systems might produce. The inadequacies of using conventional PI regulators for feedback closed-loop control in control systems requiring high-precision positioning has been analyzed. Starting with constructing a mathematical model of the PMSM, A simulation model has been built for the vector control system of the servo motor and designed speed feedforward and acceleration feedforward controllers. By setting up an experimental platform for the PMSM servo drive system, The significant effect of the designed feedforward controller on improving the fast response ability of the position and reducing the steady-state error of the position was verified.
