AC位置伺服系统解耦—变结构控制器的研究

Research on a Decoupling—Variable Structure Controller of AC Position Servo System

本文提出了AC位置伺服系统的解耦—变结构控制器,给出了一种克服转子电阻值随温度变化而增大对解耦控制产生的不利影响的方法。从而保证了解耦控制转矩完全正比于转子电流的特点,很好地满足了位置伺服系统对动态、稳态性能及鲁棒性的基本要求。

In this paper,a decoupling—variable structure controller of ACposition servo system is presented.At the same time,a method is given toovercome the unfavourable influence upon decoupling control which come fromthe rotor resistace due to the increase of temperature.So the torque referenceis proportional to the torque current completely.The basic requirement of ins-tantanous,stable performauce and robustness to position servo system is fullysatisfied.
