Simulation for Vehicle Active Suspension Control Based on Different Feedback Parameters
نویسندگان
چکیده
A half-car model with four DOF was established to simulate the system. On the basis of this model, Selfadapt Parameters Fuzzy-PID control method of the active suspension system is described. In such a model, vehicle speed, vehicle body vertical acceleration, suspension dynamic deflection, the body vertical acceleration and suspension dynamic deflection integrated feedback were used respectively as the integrated feedback. The simulation results show that active suspension Self-adapt Parameters Fuzzy-PID control with the body vertical acceleration and suspension dynamic deflection as comprehensive feedback parameters compared with passive suspension can improve the ride comfort and driving stability in random excitation.
