基于PID算法的电动车跷跷板系统设计

his system adopts P89V51RD2 microcontroller as the core, the stepper motor as the drivers which is driven by L298 chip, the rudder to change the veer and the angle sensor to detect the transformation of the teeterboard. The infrared detection module is designed fore-and-aft the car.Via taking count of the pulse infrared photoelectric code board determine the location on the board. Infrared remote control keyboard boot the system into operation, and liquid crystal display information about relevant parameters. The balance regulation of the system us the digital PID control algorithm, using experiment to install PID parameter. Through the changed angle measured by angle sensor the stepper motor is controlled to make the teeterboard achieve balanceable state.
