摘要
根据改进的离散趋近律设计了位置随动系统的滑模变结构控制算法,仿真结果表明:该算法不仅实现了系统对位置信号的跟踪,还克服了常规离散趋近律参数选择不当出现的抖振现象,是一种具有应用价值的非线性控制方法。
Sliding mode variable structure control algorithm is designed for the position-tracking system on the basis of improved discrete reaching law. Simulation results show that the algorithm not only enables system to track position signal, but also avoids chattering caused by inappropriate parameter for the conventional discrete reaching law.
