An improved algorithm is put forward based on the fuzzy adaptive algorithm presented in paper [1]. According to the inproved algorithm, without breaking global stability, the supervising part u s can be deleted, while a differential part u a can be added to improve the transient response. A type of structure self organizing algorithm is presented to guarantee close loop asymptotical stability. Simulation results show that, compared with the algorithm in paper [1], the algorithm in this paper is easier to satisfy the stability condition and has better transient response.
