Abstract: Aiming to avoid the skidding of a moving electric pallet truck, a new anti-skid method was proposed in this paper, which changes the proportion of enduring pressure between the driving wheel and trundles of the electric pallet truck. And a hydraulic anti-skid system was built up according to this method. Based on the theoretical analysis of the hydraulic anti-skid system, simulations were carried out by using AMESim and Matlab/Simulink software, and the anti-skid experiments were implemented. The results of simulations and experiments all show that the designed hydraulic anti-skid system can prevent trucks from slipping and can realize accurate and real-time anti-skid control.

Abstract: According to the mathematical model of brushless DC motor (BLDCM), control equations of BLDCM speed control system and simulation model were established for steering control device in electric pallet truck based on transfer function in Matlab/Simulink. The fuzzy adaptive PID control method was introduced to speed control system, and it can realize PID parameter’s online adjustment. Simulation result shows that the designed speed controller based on fuzzy adaptive PID has better dynamic and static performance than the controller based on traditional PID, and the control accuracy is also greatly improved.

Abstract: Based on electric pallet truck skids in the process of moving because of low road attachment coefficient, this paper proposed an anti-skid method by changing the proportion of enduring pressure between the driving wheel and trundles. Anti-skid control theory of the new method is researched and mathematical models of the main modules are established. Anti-skid control system is simulated by using AMESim and Matlab / Simulink software. Simulation results show that, this hydraulic anti-skid system can respond quickly and precisely.
