高瞬态响应指标的伺服系统设计方法

提出了一种高瞬态响应指标的伺服系统设计方法。经典的伺服系统设计方法,采用小时间常数处理技术,这种处理引入误差大,导致设计的伺服系统瞬态响应指标不高。为了设计出高瞬态响应指标的伺服系统,提出用比例微分单元对消掉较大时间常数的极点,同时降低小时间常数处理引入的误差,然后按照典型Ⅰ型与Ⅱ型系统的设计准则设计系统的调节器。通过仿真实验对比证明,该方法能够设计出具有高瞬态响应指标的伺服系统。

Design Method of Servo System Possess of Fast Transient Response

This paper presents a servo system design method with high transient response performance.Classical servo system design uses small time constant method which introduces biggish error,thus leading to a not high transient response index for design of the servo system.In order to design a high transient response servo system in this paper,the proportion differential element is used to eliminate the larger time constant of the pole.At the same time,errors introduced by small time constant processing are reduced.Then according to design criterion of the typical type 1 and type 2 system,a regular of the system is designed.The comparing simulation experiment proves that this design method can be used to design fast transient response servo system.
