中文摘要: 位置跟踪是速度控制基础上一个更高层次的控制,是电机控制的一个重要方面。由于开关磁阻电动机(SRM)设计和控制的特点,SRM具有很强的非线性,这使得SRM很难应用于高性能的位置控制。在传统的位置控制中,由于电机的转速和位置具有明确的关系,实现电机独立的速度控制非常困难。项目首次将速度可控性的理念引入SRM的位置跟踪控制,主要解决四个方面的问题:第一、如何将速度控制自由度引入SRM位置跟踪控制,保证SRM跟踪速度具有外部可控性;第二、在速度可控的前提下采用什么控制方法设计SRM位置跟踪控制器,便利于速度可控位置跟踪的设计实现;第三、针对SRM的位置跟踪,如何有效抑制SRM的转矩脉动以提高位置跟踪的性能;第四、在控制器的设计过程中采用什么手段降低负载转矩对于位置跟踪性能的影响。项目的研究为解决SRM位置控制问题提供了一个很好的思路,同时该方法在其他类型电机位置控制方面的应用也具有非常重要的意义。

英文摘要: Position tracking control is a more higher level control based on the speed control. And it is a very important aspect of the motor control. Because of the characteristics of design and control, switched reluctance motor(SRM) has strong nonlinearity. This makes it a difficult task to realize high performance position tracking control of the SRM. In the traditional position control, the motor speed and position has definite relationship which makes the independent control of motor speed more difficulty. In this project, the concept of speed-controllability is introduced in the position tracking control of the SRM firstly. The aim of the project is to solve four main problems. The first problem is how to introduce the speed control freedom into the position tracking of the SRM to guarantee the tracking speed has outside controllability. The second problem is which control method can be adopted to design the position tracking controller of SRM based on speed- controllability, and the method is convenient to the realization of the position tracking control with speed controllability. The third problem is how to effectively restrain the torque ripples of the SRM to enhance the performance of the position tracking. The fourth problem is which method can be adopted to reduce the effect from the load torque in the desig
