| 摘 要： | 本文根据变结构系统(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,并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)对系统参数变化具有鲁棒性;(3)对外界干扰具有鲁棒性。

| Abstract: | An aircraft servo loop is designed from the variable structure system (VSS) theory with a detailed procedure of a controller design and an intuitively geometrical sense of the design method . A digital simulation with block diagram is done by means of IBM 4341 computer, and the control performance is compared with the original servo loop. The simulation demonstrates that some outstanding advantages of VSS over the general control system are as follows.(1) a rapid transient response without overshooting and steady error.(2) robustness in varying system parameters.(3) robustness against the outside disturbance. |
