Feedforward Control with On-line Parameter Identification in the AC Position Servo System

The tracking control based on the feedforward control in the AC position servo system was discussed in this paper. An improved on-line parameter identification scheme was proposed to identify model parameters fast and effectively, and apply them to feedforward controller. It was proved by the research that the feedforward control with online parameter identification can achieve high-speed high-precision tracking control in the position servo system.
