摘要
本文阐述了结构半主动控制的概念，并介绍了国内外有关结构半主动控制的研究状态，阐述了几种有关结构半主动控制的算法，包括基于经典最优控制的控制律及算法、基于变结构系统（ＶＳＳ）现论的滑动模态控制算法和非线性奇次系统的ｂａｎｇ－ｂａｎｇ控制算法，重点阐述了变结构系统（ＶＳＳ）理论和滑移面的确定及控制律的设计。
In this paper, the cancept and state -of- the- art of semi- active structural control is expounded. Several control laws and atlgorithms used for serd -active struciural cdntrol are discussed. These include (1) control law and algorithm based on classical optimal control: (2) sliding mode control (SMC) hased on variable structure systems (VSS); (3) bang -bahg control of nonlined. homogeneous systems. Emphasis is placed on sliding mode control. The detail of design of the sliding surtbce and design of the controller using Lyapunov direct method are given.
