摘要
A two level optimization strategy is proposed fur fuzzy control design in this paper. The phase-plane of dynamic system is firstly divided into two-lever nonlinear regions according to response analysis, then a neuro-fuzzy hybrid network is built to optimize the region lever by lever, By the former, control process is decomposed properly, quick dynamic response and stable steady state with high accuracy are achieved coordinately, While through the later, unreasonable factors in the design of fuzz? control are decreased/eliminated and effect of fuzzy control is improved by learning. It offers a general, simple and efficient way for fuzzy control design. The optimized fuzzy controller is adopted in an electrohydraulic servo system, and satisfactory performance is obtained.
