本文讨论了开关磁阻电动机（SRM）驱动系统中的一个基本控制问题-无脉动转矩的产生。简单的和很大程度上与模型无关的传统电源波形不能满足这一要求。本文的目标是改善SRM的动态性能，通过补偿电机的非线性，同时保持传统方法的鲁棒性。该方法是基于一个完整的参数化的位置相关的电压和电流分布在无纹波操作，并在波形优化，以尽量减少电源的要求。此外，模型的不确定性，包括表明，所提出的战略始终优于传统的政策。实验数据验证的分析方法。
This paper addresses a basic control issue in switched reluctance motor (SRM) drives-the production of a ripple-free torque. Simple and largely model-independent conventional supply waveforms are not able to satisfy this requirement. The goal of this paper is to improve SRM dynamical performance by compensating for motor nonlinearities, while maintaining the robustness of conventional methods. The method is based on a complete parameterization of position-dependent voltage and current profiles in ripple-free operation, and on a waveform optimization to minimize power supply requirements. Furthermore, model uncertainties are included to show that the proposed strategy consistently outperforms the conventional policy. Experimental data verifying the analytical approach are included.
