The adaptive backstepping control of PMSM supplied by current source inverter for the field weakening region
Abstrakt
The sensorless control system of permanent magnet synchronous motor PMSM supplied by current source inverter for field weakening operation is presented in this paper. The adaptive backstepping control system and the backstepping speed observer are presented. The control system is based on multi-scalar variables. The control variables are: dc-link voltage and the output current vector pulsation. The control system was named voltage control system because of the fact that the first control variable is voltage in dc-link. The machine inverter is treated as commutator. It works with constant modulation index. Proposed control system is robust on mechanical and electromagnetical parameters of the motor. The adaptive estimator of the stator resistance and stator inductance are introduced. Such an approach to control of PMSM motor gives better performance. It is robust to dynamic uncertainties and does not require knowledge of the system parameters. The mathematical equation was introduced. The field weakening with adaptive control was not well known. In field weakening the reference torque or current must be limited when the rotor speed is near nominal. The method of control variables limitation in the backstepping control system is shown. The mathematical dependences based on multi-scalar model for field weakening method are presented. The simulation and experimental tests are confirmed the good static and dynamic properties of PMSM supplied by a current source inverter with the adaptive backstepping control system.
