摘　　要：为了实现雨刷的精准定位和控制,设计了一个风挡雨刷控制系统.系统采用脉宽调制(PWM)实现直流电机的调速,采用改进的PID、模糊控制算法对雨刷进行精确的同步定位控制,实现了单个雨刷的低速、高速、间歇、停止4个档位控制及左右雨刷的同步.测试结果表明,雨刷在低速、高速、间歇档位时频率分别为12,20,10循环/min,误差小于1循环/min,该控制系统性能稳定、同步控制效果良好,达到了预期的精度要求.In order to achieve the precise positioning and control of the wipers,a control system of windshield wipers is designed.PWM is used in the system to achieve the speed control of DC motor.Improved PID and fuzzy control algorithm are adopted in precise synchronization wipers positioning control to achieve low speed,high speed,intermittent and stop gears of a single wiper and the synchronization control of the two wipers.Results show that the frequencies of low speed,high speed and the intermittent gear are 12,20,10cycles/minute,the error is less than 1cycle/minute,the control system is stable to achieve the desired accuracy and the synchronization control system works well.
