| 摘 要： | 研究离散时间系统变结构控制问题,提出一种新的离散变结构趋近律.利用该趋近律设计的离散变结构控制器,不仅能大幅度削弱抖振,使系统运动最终趋干原点不存在稳态振荡,而且可使系统的准滑动模态保持步步穿越切换面的基本属性,有效地改善了控制品质,提高了系统的鲁棒性.仿真结果验证了该方法的有效性与合理性.

| Abstract: | The problem of variable structure control for discrete-time systems is considered.A new discrete reaching law is presented.The discrete-time variable structure control system,which is designed by this reaching law,not only can weaken the chattering and approach to zero diminishingly,but also can keep the basic property of quasi-sliding mode which can cross the switching surface step by step and enhance the control quality and robust performance of the control system.The simulation results validate the effec... |
