【摘要】 提出离散变结构控制系统基于衰减控制的变速趋近律。该控制算法结构简单,可以期待原点稳定,并且当选择合适的控制器参数后,具有良好的动态和稳态特性。研究该种控制方法在空间大型离心机动平衡控制系统中的应用。仿真结果表明,控制效果较好,满足控制精度指标要求,可以使系统渐进稳定于目标状态,大大缩短到达切换面的时间且能有效抑制抖振。更多还原

【Abstract】 Aiming at the attenuating control,the variable structure control for discrete time system based on attenuating variable rate reaching law is proposed.It can be expected to converge to the original point and has good dynamic and static characteristics when appropriate controller parameters are chosen.The application of proposed control method for the automatic balancing control system of space large-scale centrifugal machine is researched.The simulation demonstrates that the control effects are fairly good and the indexes of control precision are fulfilled.更多还原
