| 摘 要： | 研究离散变结构控制理论及其在直流伺服系统中的应用问题.对传统离散趋近律方法稳态振振的原因进行分析,提出一种对传统离散趋近律施加一约束条件的方法.理论分析及仿真研究结果表明,该方法可以有效减弱抖振强度,提高系统的稳态精度.利用该方法设计的离散变结构控制器能够使伺服系统快速、准确地跟踪给定信号,并对参数摄动和外部干扰具有很强的鲁棒性.

| Abstract: | The design of quasi-sliding mode controller for DC servo system using discrete variable structure control theory was discussed in this paper. The reason for system chattering of conventional discrete reaching law approach was studied and a new control strategy was proposed. Theoretical analysis and simulation results show that the controller designed here can eliminate chattering effectively and make the servo system have perfect tracking ability and strong robustness. |
