Two closed-loop fuzzy controller for driving system in electric minicar

Aimed at complexity and uncertainty of electric minicar driving system, such as vehicle velocity, road condition, environment disturbance, storage battery and given signal etc., which are uncertain, cross-relative, nonlinear and time-varying, it is very difficult to describe it through mathematic model. Therefore, Authors select fuzzy control as control strategy, apply single chip processor to implement hardware, adopt two-dimension fuzzy control pattern, whose input variables are error and change of error, respectively, through querying list algorithm to realize fuzzy inference. On the basis, developing corresponding fuzzy control system, whose structure adopted two closed-loop, the result shows that effect of control is satisfied.
