摘要
Abstract
The rotor flux will be changed to obtain the maximum ratio between torque and stator current,under the maximum toque per ampere (MTPA) criteria.Since flux changes with reference torque,not a constant as in conventional vector control algorithm,nonlinear magnetic saturation effect cannot be ignored.In this paper,a control system considering magnetic saturation effect is proposed.Optimal reference rotor flux is found using linear search algorithm,while the rotor flux is estimated using reduced order observer.The observer-error is taken into consideration,when designing flux controller using sliding mode algorithm and torque controller using backstepping algorithm,to ensure the global stability.Simulation and experimental results show the effectiveness of the proposed algorithm.关键词
