汽车雨刷系统的PID控制

Controlling the Windscreen Wiper System of the Automobile by Using PID

雨刷器是汽车的重要部件之一,基于PID控制的汽车智能雨刷系统,通过红外传感器感知雨量的大小,运用单片机的PWM信号控制雨刷器工作在高速或低速状态,采样PID控制器能明显改善系统的稳态和动态性能,实验证明,该系统性能可靠、控制效果良好.

The windscreen wiper is an important part of the automobile, and the intelligent windscreen wiper system of the automobile is based on the PID controller. This system senses the amount of rainfall by the infrared rain sensor and thus makes the windscreen wiper automatically work either at a high speed or at a low speed state by the PWM signal of the MCU. It can obviously develope the static state and dynamic state ability of the system by using PII） controller. Experiments show that the intelligent windscreen wiper system is sensitive and has good performance.
