| 摘 要： | 针对常规指数趋近律单向辅助面滑模控制中存在的抖振问题, 提出了一种基于变指数趋近律的单向辅助面滑模控制方法。针对系统控制量变化时飞机模型发生跳变的问题, 进行T-S 模糊建模, 以保证非线性系统在控制区间上的平滑性; 在对UAS-SMC(Unidirectional Auxiliary Surfaces-Sliding Mode Control)方法进行分析的基础
上, 给出了一种变指数的趋近律; 结合飞机模型和变指数趋近律, 设计了基于变指数单向辅助面滑模控制器。仿真实验结果表明, 该控制策略能保证趋近过程快速性的同时在接近滑模面时能有效减少系统的抖振。

| Abstract: | A control scheme is proposed based on improved exponent trending law to deal with chattering problem in UAS-SMC(Unidirectional Auxiliary Surfaces-Sliding Mode Control). First, to ensure the smoothness of system in the control range, T-S model is built to deal with aircrafts model change with control variable. Then an advanced sliding mode control with unidirectional auxiliary surfaces is analyzed, and an improved exponent trending law is proposed. The control scheme is designed based on fuzzy model and the new trending law. The simulation results show that the scheme can guarantee the rapidity of approaching process and suppress the chattering effectively. |
