A theoretical and experimental analysis of a closed-loop adaptive velocity control system for a 200 W permanent-magnet synchronous motor (PMSM) is presented. The control system utilizes 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 in detail. It is shown that the real-time observer-based adaptive velocity controller is capable of successful operation. >
