| 摘 要： | 开关磁阻电机（switched reluctance motor, SRM），因为它的特殊构造，以及磁路的饱和性，使得SRM成为了多变量、非线性，以及强耦合的系统，它的磁链、电流、转矩和转子角度之间都存在着复杂的非线性关系。反步法作为一种处理非线性系统控制的高效控制策略，具有高效和鲁棒性的特点，在本文中，选用的是三相6/4开关磁阻电机进行研究，根据SRM准线性公式设计了反步控制模块，接着再利用李雅普诺夫稳定性理论证明了它的稳定性，提出基于反步法的SRM电流斩波控制的方法，通过MATLAB/simulink进行仿真，仿真的结果可以看出在电机启动的时候，电流在80 A上下波动，形成了平顶波，证明了该方案的合理性，为实际SRM电流斩波控制系统的设计提供了另一种思路。

| Abstract: | SRM is a multivariable, nonlinear and strong coupling system because of its special structure and magnetic circuit saturation, the flux linkage, current, torque and rotor angle has a complex nonlinear relationship. As a kind of efficient strategy for dealing with nonlinear system control, the Back stepping Control method is efficient and robust. In this paper, three phase 6/4 SRM is selected to research, according to SRM formula to design the back strpping control model, using Lyapunov stability theory and proves its stability, proposed SRM current chopping control based on back stepping method, through MATLAB/simulink simulation, the simulation results show that when the motor is started, the current fluctuation in the 80 A up and down, forming a flat top wave, it is proved that the proposed method is reasonable, and provides another idea for the design of the actual SRM current chopping control system. |
