Takagi-Sugeno(T-S) fuzzy model of hydro-turbine governing system and a new identification method based on chaos optimization strategy are proposed.Considering the close connection of premise parameters and consequent parameters of T-S fuzzy model,the identification method is presented identifying them simultaneously,identifying the consequent parameters with least square method and identifying the premise parameters with chaos optimization strategy,which realize the adaptive optimization of T-S fuzzy model.The results of identification and simulation of T-S fuzzy model of the hydro-turbine system show that the identified fuzzy model has relatively high precision and good generalization ability;the identification method is valid.
