Research on inteligent control technique of the paver´s traveling system

In order to improve the performance of crawler paver´s traveling, a new control plan of paver´s traveling system was proposed. In the control plan, the left wheel control method adopted velocity closed loop control in order to keep constant-Speed Moving of the paver. The right wheel control method adopted the series structure of fuzzy control and PID control in which the fuzzy controller slightly adjusted the right wheel set-point of PID controller according to the distance difference variable and velocity differences variable of paver´s left wheel and right wheel. The experiment results show that a new control plan made the paver´ distance difference index when running straight 50m reduce from 2% to 0.5%.
