Control Algorithm Research on Smart Car Based on Fuzzy PID

During the process of smart cars automatic searching the way,serious nonlinear problems exist in direction control and speed control.This paper implements the fuzzy PID algorithm,namely we use fuzzy PD algorithm to control the direction and use fuzzy PID algorithm to control the speed.The result shows that some defects of traditional PID control have been overcame.The real optimization of the control parameter of PID controller has been carried out by fuzzy reasoning.
