定子双馈电双凸极电机的模糊自适应PI控制

定子双馈电双凸极(SDFDS)电机具有结构简单可靠,功率密度高,可控参数多,容错性能好等优点。但它的转矩和转速之间具有强烈的非线性关系,采用常规线性PI控制器难以得到令人满意的控制特性。针对这个问题,结合模糊控制灵活、鲁棒性强的优点和PI控制精度高的特点,设计了模糊自适应PI控制器,并通过仿真和实验与传统的PI控制器和模糊控制器进行了比较。结果表明,模糊自适应PI控制器继承了模糊控制和PI控制的优点,能获得优良动静态性能和适应性。

Fuzzy adaptive PI control of stator-doubly-fed doubly salient motor

Stator-doubly-fed doubly salient(SDFDS) motor has the advantages of high reliability,high power density,fault tolerance and simple structure.But it is difficult to get satisfied control characteristics by using normal linear proporition integral(PI) controller due to the high nonlinearity between speed and current or torque.To solve this problem,a fuzzy self-adaptive PI controller is designed by combining the strength of high flexibility and high robustness of fuzzy controller with the strength of high precision of conventional PI control.The simulation and experimental results verify that the fuzzy self-adaptive PI controller can inherit the advantages of the fuzzy controller and the conventional PID controller,improve the dynamic and the static performance and adaptability of the SDFDS motor drive significantly.
