中文摘要：
针对单绕组磁悬浮开关磁阻电动机非线性、多变量、强耦合的特点,提出一种将支持向量机逆系统方法与内模控制相结合的非线性解耦控制策略。该方法通过支持向量机离线优化学习构建系统α阶逆模型,将优化的支持向量机逆模型与原系统复合,将其解耦成两自由度位移和转速伪线性子系统;为了提高系统的抗扰性和鲁棒性,对解耦后的伪线性系统引入非线性内模控制。仿真和实验研究验证了所提控制方法的有效性。
英文摘要：
The single winding bearingless switched reluctance motor（ BSRM） is a nonlinear,multi- variable and coupled system. For this system,a new decoupling control strategy that combines the support vector machine αth- order inversion and internal model control was proposed. By cascading the αth- order inverse model built by the least- squares support vector machine with the original system,the single winding BSRM system was decoupled into two radial displacement subsystems and a speed subsystem. Then,to enhance the robustness and anti- disturbance ability of the control method,the internal model control was introduced to the subsystems. Finally,the effectiveness of the proposed strategy was demonstrated by simulation.
