摘要: 根据变结构系统(VSS)理论对某飞行器伺服回路进行了变结构设计,给出了控制器设计的详尽步骤,设计方法几何意义直观,在IBM4341机上通过了数字仿真,给出了仿真框图;与原伺服回路的控制性能进行了比较。仿真表明,VSS比传统普通控制系统具有以下几个突出的优点:(1)快速、无超调、无稳态误差;(2)对系统参数交化具有鲁棒性;(3)对外界干扰具有鲁棒性。

Abstract: An aircraft servo loop is designed by using the variable structure system (VSS) theory. The detail design procedure and a simulation block diagram are provided. Then digital simulation results which was done on IBM4341 computer show that some outstanding advantages of VSS comparing with general control systems are as follows: ( 1 ) a rapid transient response, no overshoot, no steady error. ( 2 ) more robust to the varience of system parameters. ( 3 ) more robust to the outside disturoences.
