Heavy Truck EPS System Simulation Based on PSO Optimization Fuzzy Control

Based on particle swarm optimization of heavy truck EPS system control strategy is proposed, on the basis of vehicle EPS system overall design, taking DC motor current as the control target, using particle swarm optimization fuzzy control strategy, using MATLAB/Simulink as simulation platform, taking dump truck as research type models and commercial vehicle simulation model which equipped with EPS system is established. The simulation experimental results show that compared with the conventional fuzzy control, particle swarm optimization fuzzy control can improve the whole dynamic response of heavy truck EPS system efficiently, also good steering portability and handling stability is obtained.
