| Abstract: | In order to study the dynamic characteristics of automobile with a CVT system, a bond graph analysis model of continuously variable transmission is established. On the base of the simulation state space equations that are established with bond graph theory, a fuzzy control strategy with an expert system of starting process has been introduced. Considering uncertain system parameters and exterior resistance disturbing , the effect of the profile of membership function and the defuzzification algorithm on the capacity of the fuzzy controller has been studied. The result of simulation proves that the proposed fuzzy controller is effective and feasible. Such controller has been employed in the actual control and has proved practicable. The study lays a foundation for design of the fuzzy controller for automobile with a CVT system. |
