Design and simulation of the Fuzzy-PID controller based on single wheel vehicle suspension

We make a study of the control on vehicle active air suspension.On the foundation of conventional PID controller for vehicle active air suspension,we make a on-line parameter-revise to conventional PID controller by using Fuzzy reasoning and design Fuzzy-PID controller based on single wheel active air suspension.Using matlab/simulink module,we make modeling and simulation of single wheel active air suspension.The simulation results show that,Comparing with single wheel passive air suspension and single wheel active air suspension with the conventional PID controller,aingle wheel active air suspension with the Fuzzy-PID controller can improve vehicle ride comfort,handling stability,and have good robustness.
