Modelling and simulation of a fuzzy PID controller for active suspension system

This paper design the active suspension considering four connected subsystems- mechanical subsystem, control subsystem, electronic subsystem and hydraulic subsystem. Electrodydraustatics actuator (EHA) which is widely used in Power-By-Wire (PBW) system is applied to active suspension in this article instead of traditional hydraulic valve components. After the modeling,the active suspension fuzzy PID controller are designed and the computer simulations are built in Matlab. And then the quarter-car active suspension system has been simulated and better results has been achieved.
