摘要：he Smooth of the shuttle vehicle speed control system is the guarantee of the safe operation of the car body, the current shuttle vehicle parking in the start acceleration and deceleration will happen when the shaking phenomenon, It reduces the shuttle car shelf system security and stability. The S-curve to add and subtract in the simplified method is applied to speed regulation system of shuttle car, can reduce the occurrence of this phenomenon. But the S-curve algorithm without considering the bodies weight and load change on the result of speed regulation. In this paper, we improve the S-curve and speed reduction algorithm. Considering the factor of the weight of the vehicle and the load factor, realize the smooth control of shuttle car. This paper introduces the method and principle of the speed control of shuttle car. An improved method for calculating the S curve acceleration and deceleration is presented. And Matlab simulation is carried out. Results of simulation and actual equipment show that the improved algorithm can control the smooth running of the shuttle vehicle.
