一般频率依存数字最优预见伺服系统

A General Frequency Dependent Digital optimal Preview Servo System

本文研究了一般类型的频率依存数字最优预见伺服系统，给出了这类系统的设计方法．按照所给的方法，无论目标值信号与输出信号间的误差向量前附加一个什么样的有理分式形频率依存荷重，都可以针对它设计最优预见伺服系统．本文还通过数值仿真，把所得结论应用于直线电机，证明了方法的有效性．

In this paper,we present a design method for a kind of general frequencydependent digital opt imal preyiew servo system wb ich is effectiye to improyefrequency character istics of closed loop.system.By the method,for ally rationalexpression frequency dependent weight.which loads on error vector, we can designan optimal preview servo system.The result is applied to an air slide linearmotor in simulation and its effectiyity is proved.
