This paper uses two MacPherson struts and one fluidic muscle actuator (FMA) to design a fluidic muscle active suspension system (FMASS), allowing to provide active complementary force to suppress road vibration and improve ride comfort for passengers. The FMA outputs an additional force accompanying with the MacPherson struts so that FMASS has much powerful strength to stabilize the vehicle body. To regulate the vehicle body, a parallel type adaptive interval type-2 fuzzy sliding mode control (parallel-AIT2FSC) is presented in this paper. It has two AIT2FSCs in parallel: one controls the position and the other reduces acceleration. A fully functional test-rig is constructed to verify the feasibility of the FMASS using self-generated road conditions. In the experiments, the characteristics of the FMASS, such as the position and the vertical acceleration of the sprung mass, are demonstrated on two different road conditions and are presented in the time and frequency domains. The experimental results show that the vibration on the chassis is greatly reduced.
