With the rapid development of electronic control technology, the increasing requirements for vehicles' drive, economic and emission performances propel the application of Electronic Throttle System (ETS), which can achieve accurate closed-loop control for throttle open angle. In this paper, the non-linear factors, such as spring torque, friction, intake resistance and gear clearance, are taken into account during the derivation of ETS model. Five controllers are designed in Matlab/Simulink, using PID, fuzzy, sliding model control approaches and their combination. Then step input simulations are performed and their response characteristics are compared, which are validated in the SGMW B12 engine test rig.
