A Smart Wiper System Based on Feedforward-Feedback Composite Controller
Abstract:
The velocity of the wiper arms is a key factor which can influence the clarity of the windshield and the comfort of the driver’s view. So how to control the velocity of the wiper arms is important. To solve the problem, a method is elaborated based on feedforward-feedback composite controller. It introduces the hardware and software design based on the feedforward-feedback algorithm, controlling the velocity of the wiper arms by adjusting the duty of PWM. The experimental results indicate that the smart wiper system is reliable, and has good accuracy and real-time performance.
