Feedforward Improved PID Algorithm to Control the Smart Car

Abstract:

In the self-designed smart car, to control the speed and direction is the control core of the intelligent vehicle system . Due to hardware limitations, there is a delay in the smart car speed and direction control, which is adversely affected for the control of the smart car . For the above problems, the intelligent vehicle control will be applied by the feedforward and feedback control methods, the disturbance which is caused by the deviation will be treated in advance, Digital PID algorithm is improved , the incomplete differential and differential current algorithm is introduced to the PID algorithm to improve the dynamic performance of the system. Aftet this new algorithm is adopted, the dynamic performance of the intelligent vehicle system has been greatly improved.
