Application of Fuzzy Algorithm in Smart Car

In the smart car which is designed by myself,Serious nonlinear problems exist in direction control and speed control.This paper implements the optimal control to direction and speed control by combining fuzzy algorithm and PID The meaning of the albreviation algorithm,namely we use fuzzy algorithm to control the direction and use fuzzy PID algorithm to control the speed,so that the smart car can make the appropriate decision-making based on the change of the track.The control strategy of this paper is programmed on MC9S12DG128B which is a kind of the Freescale MCU.Experiments show that the smart car,which adopts the fuzzy algorithm,improves the adaptability to the track and the stability of control greatly.This method has good effect to the smart car.
