Adaptive Position Control of a Synchronous Drive fed by a ZVS PWM Inverter, using On Line Identification and Self-Tuned RST Controller

A performant position control method for a synchronous drive is presented. This method is based on a self-tuned RST controller using on line identification. At first, the RST controller structure is described assuming a no process identification. The regulator's design is based on a pole placement strategy. The on line identificaiton based on the recursive least-squares algorithm is then introduced. Finally, the study focuses on the implementation of the adaptive control. The drive's performance with regard to load torque variations is then analysed, this for different initial tuning gain values.
