Abstract: Fuzzy Sliding model control (FSMC) has been suggested to control hydraulic actuated nonlinear active suspension using full car model. The development of efficient classical controller for active suspension has been difficult due to complex nature of full car mathematical model, nonlinear effect in suspension and unpredictable behaviour of hydraulic actuator. The sliding mode controller (SMC) has an ability to handle uncertain parameter, nonlinearity and complex mathematical model of dynamic system. Chattering phenomenon remains to be the only obstacle for nonlinear sliding mode controller which can be eliminated by integrating fuzzy logic with sliding mode control. In this work, fuzzy sliding mode controller proposed for hydraulic actuated nonlinear active suspension to handle nonlinearity, uncertainty in parameter variation and chattering effect. The simulation is carried out using Seven degree of freedom based full car model to measure body displacement, acceleration, roll and pitch angle of vehicle. The response of full car model confirms the feasibility of fuzzy sliding mode controller for hydraulic actuated active suspension.
