基于超扭曲滑模的双定子绕组感应电机转速磁通控制
Speed and Flux Control of Double-stator Winding Induction Machine Based on Super Twisting Sliding Mode
摘要
Abstract
In view of the problems of dual-stator winding induction machines(DSWIMs)under traditional direct torque and flux control such as large torque,large flux and large current ripple,and considering that it is difficult to control the flux at low speed and the corresponding noise level is high,a novel direct control method for speed and flux based on super twisting sliding mode controller(STSMC)is proposed for DSWIMs.A nonlinear controller with zero convergence error in finite time is designed,which meets the Lyapunov stability condition.On this basis,a novel torque allocation algorithm for DSWIMs is put forward,which can make the DSWIMs run in a wider speed range,including zero speed.The electromagnetic torque is provided by two sets of winding according to its rated power.In addition,a full-order observer based on sliding mode control is designed for DSWIMs,which can accurately estimate the winding flux,flux angle and rotor speed to achieve the optimal flux state.Finally,an experimental test was carried out on a 3.3 kW DSWIM drive system to evaluate the performance of the proposed DSWIM control scheme.Experimental results show that the proposed control method,torque allocation algorithm and full-order observer were effective in different speed regions.关键词
