摘要
针对双定子绕组感应电机DSWIMs(dual-stator winding induction machines)在传统直接转矩和磁通控制下转矩、磁通和电流纹波大,在低速下控制磁通难度大、噪声大等问题,提出 1 种基于超扭曲滑模控制器STSMC(super twisting sliding mode controller)的DSWIMs新型转速和磁通直接控制方法.通过设计满足李雅普诺夫稳定条件的有限时间收敛误差为 0 的非线性控制器,提出 1 种 DSWIMs 新型转矩分配算法,可使 DSWIMs在较宽的转速范围内运行,并包括零转速,所需电磁转矩由2组绕组根据其额定功率提供.此外,针对DSWIMs设计了 1 种基于滑模控制的全阶观测器,能够高精度地估计绕组磁通、磁通角和转子转速,以实现最优磁通状态.最后,在1个3.3 kW DSWIM驱动系统上进行实验测试,评估所提DSWIM控制方案的性能,实验结果证明了所提控制方法、转矩分配算法和全阶观测器在不同速度区域的有效性.
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.
