开关磁阻电动机的控制通常是基于电感随位置的变化曲线。本文讨论的问题，获得最佳性能的SRM中存在的参数变化，可以改变相电感分布。SRM驱动器的操作被认为是在受控电流模式从零到基本速度。提出了新的自整定算法，它优化了驱动器的稳态性能，以每安培转矩（TPA）为衡量标准。计算机模拟表明最优TPA问题的解的存在性和唯一性。在速度控制驱动系统的背景下，解释了新的控制策略的应用。实验结果证明了自校正控制器的有效性。
The control of the switched reluctance motor (SRM) is usually based on the inductance profiles as a function of position. This paper addresses the problem of obtaining optimal performance from an SRM in the presence of parameter variation which can alter the phase inductance profiles. The operation of an SRM drive in the controlled current mode from zero to base speed is considered. New self-tuning algorithms are presented which optimize the steady-state performance of the drive as measured by torque per ampere (TPA). Computer simulations are employed to show the existence and uniqueness of a solution to the optimal TPA problem. The application of the new control strategy is explained in the context of a speed controlled drive system. Experimental results are provided to demonstrate the validity of the self-tuning controller.
