Automatic Windshield Wiper Control System using MATLAB

This paper discusses the design and simulation of an rain sensor which automatically senses rainfall intensity and controls the speed of the windshield wiper using a PID controller. The system automatically detects intensity of rainfall by means of a simulated sensor which then controls the speed of the wiper motor according to the rain level inputs ensuring quick adaptation to environmental changes. The closed-loop control system is implemented in simulink and the PID controller enhances the precision, ensures system’s stability, and dynamically adjusts speed of the wiper motor resulting in continuous and efficient wiping under fluctuating rain levels.
