Title: Intelligent Approaches for Control of Nonlinear Plants with Significant Time Delay
Keywords: genetic algorithms; nonlinear plant; parallel distributed compensation; Takagi-Sugeno-Kang model; temperature control; time delay compensation
Abstract: The nonlinear plants with significant time delays are difficult to be controlled by classical means. In the present paper intelligent approaches are applied for the design of a nonlinear Smith predictor for compensation of the plant time delay based on a Takagi-Sugeno-Kang plant model and a fuzzy logic parallel distributed compensation (PDC). The design and the advantages of the PDC-Smith are illustrated in temperature control. The good compensation of both the plant time delay and nonlinearity results in faster system step responses in regard to a linear PI, a Smith and a PDC control systems.
