Abstract :
This paper mainly studies the speed control for a permanent magnet synchronous motor system. The relationship between the reference quadrature axis current and the speed output is approximately considered as a second-order model. Based on this second-order model, an adaptive sliding mode controller is designed for the speed regulation, which can provide effective control for load torque change and parameter uncertainty. Simulation results are presented to veryfy the proposed method.
