基于模糊控制算法的同步风挡雨刷控制器

Synchronous Windshield Wipers Controller Based on Fuzzy Control Algorithm

针对某客机风挡雨刷控制系统的设计缺陷,提出一种基于模糊控制算法的同步风挡雨刷控制器设计方案。该系统通过手动操作选择主、从两组风挡雨刷工作档位,实时捕获并记录雨刷工作周期,将主控雨刷工作周期分量T及主控与从控雨刷的工作周期差量ΔT作为模糊控制系统的两个输入量,经模糊控制系统输出主控雨刷控制信号U,实时调节主控雨刷的工作周期,从而实现两组风挡雨刷单独或精准地同步控制。

For the defects of design on the aircraft windshield wipers control system, we propose a synchronous windshield wipers controller based on fuzzy control algorithm. The system manually selects work gear from two windshield wipers, captures in re a l-time, and records wipers wo rk-cycle. The wiper＇s cycle △T of the main component and the difference wiper＇s cycle △t between the main component and the appurtenant component are chosen as two inputs of the fuzzy control system. U , as the control signal of the main component,is output by the fuzzy control system. So the cycle o f the main component can be adjusted by the real -time, in order to achieve independent or precise synchroni-zation control of the two windshield wipers.
