Robots Automobile Active Suspension Control Strategy Research and Analysis

In order to improve the car ride comfort and safety,vehicle the active suspension system.According to automobile suspended frame structure,the establishment of a two degree of freedom 1/4 body active suspension model.Because of fuzzy control has the modeling simple,high control precision,nonlinear adaptability etc,and in the vehicle active suspension control strategy has been the widespread application.Because of its structure with PID controller set flexible,parameter setting convenience,the model error robustness etc.Will their combination,this paper put forward a new control strategy.Design the velocity and acceleration in the body for the input of fuzzy PID controller,realizing the active suspension control.At the same time,using Matlab/Simulink MA computer simulation was conducted to improve the purpose of vehicle vertical vibration reduction.The simulation results show that the designed by fuzzy control strategy of active suspension system,obviously improving the vehicle ride comfort and safety.
