This paper investigates the use of Fuzzy Clustering as a means for model id
entification of a complex and highly non-linear servo-tracking system when
only observational data is available. The use of Fuzzy Clustering facilitat
es automatic generation of rules and its antecedent parameters. The consequ
ent of the model is then formulated in the form of Takagi, Sugeno and Kang
(TSK), and its parameters determined by the Least Squares Method (LSM).
