Design of Fuzzy Gain Schedulers

The design of a Takagi-Sugeno fuzzy controller (TSFC) is possible only if a Takagi-Sugeno fuzzy model (TSFM) of the open loop nonlinear system under control is provided. A survey of the relevant publications in this field reveals that a TSFM is either given for granted, or is identified on the basis of input-output data. Thus, it remains an open question how a TSFC can be designed in a systematic manner, given an open loop nonlinear model described in terms of differential equations. Another aspect of TSFC which has received almost no attention is related to its robust performance. The major problem here is to find the stability margins of the closed loop model with respect to unknown disturbances. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
