摘　　要：对液压支架油缸工作原理进行了深入分析,提出了一种能够提高其稳定性和鲁棒性的自适应控制策略。结合固定时间算法和模糊控制理论,利用反步设计方法构建了一种固定时间自适应控制器,保证被控系统在固定时间内达到稳态,且不受系统初始状态的影响。最后通过一个仿真算例验证了该方法的可行性。Deeply analyzed the working principle of the hydraulic support cylinder,and proposed an adaptive controll strategy which can improve its stability and robustness.Combined fixed-time algorithm and fuzzy control theory,a fixed-time adaptive controller was built by using backstepping design method to ensure that the controlled system reaches steady state within a fixed-time,and is independent of its initial state.Finally,a simulation example was presented to validate the feasibility of this method.
