Abstract

A theoretical and experimental analysis is presented of a closed-loop adaptive velocity control system for a 200 W permanent magnet synchronous motor. The control system utilities a mechanically sensorless full-state observer for the generation of all controller feedback information. Both the control system and its experimental performance using an implementation based on the Motorola 68020 microprocessor are presented. It is shown that the real-time observer-based adaptive velocity controller is capable of successful operation.<>
