Study of 1/2 Vehicle Active Suspension System with Fuzzy PID Controller

Zheng Shua

Abstract

1/2 active suspension of vehicle system dynamics model and road input model were established.The PID control and fuzzy control were parallel connected and the active suspension with fuzzy PID controller was designed.The simulation results in MATLAB/Simulink showed that the active suspension fuzzy PID control was superior to the passive suspension and simple fuzzy control and PID control in the aspecls of vehicle body acceleration,pilch angular acceleration,suspension dynamic travel and tire dynamic deflection,the riding comfort can be improved preferably.
