中文摘要
      研究有界不确定离散时间系统的变结构控制设计问题.对利用传统离散趋近律设计变结构控制器时出现的稳态抖振现象进行分析,提出一种能有效减弱抖振的控制策略,并将研究结果用于设计某位置伺服系统变结构控制器.理论分析及仿真结果表明,所设计的控制器可以有效减弱抖振,并使伺服系统具有良好的跟踪能力和很强的鲁棒性.
英文摘要
       The design of variable structure control using the reaching law approach for uncertain discrete time systems was discussed. The reason for system chattering of conventional reaching law was studied and a new control strategy with perfect performance was proposed. The new method was applied to a position servo system. Theoretical analysis and simulation results showed that the controller designed can weaken the chattering effectively and provide the servo system with perfect tracking ability and strong robustness.
