摘　　要：提出一种基于AVSC(近似变结构控制 )及FLCN(模糊局部控制器网络 )的鲁棒增益调度控制设计方法 .利用AVSC ,对于一般的工作点选择合适的滑动模及其趋近率 ,得到局部鲁棒AVSC控制律 ,使局部系统尽快进入滑动模 ,并具有期望的性能 ,同时能够克服一般VSC(变结构控制 )的控制信号抖动现象 .当然 ,任意一个局部控制器一般只能保证在其相应工作点附近的工作性能 .为此 ,引入了模糊控制技术的隶属函数 ,将它当作增益调度控制器的有效度函数 ,得到FLCN .仿真研究验证了所提出控制器设计方法的有效性 .Based on the approximate variable structure control (AVSC) and fuzzy local controller network (FLCN), a new design gain scheduling controller is proposed. The proper sliding modes and the tendency rates for general operation points are introduced such that the system gets into the sliding modes'motion as soon as possible and has the desired performance, and meanwhile the chattering of normal VSC can be avoided by AVSC. However, any local controller works well only in the local region of a specified operation point. The valid functions which are similar to the fuzzy attributed function in fuzzy systems, are introduced to form FLCN. The simulation results show that the presented method is feasible and acceptable.
