Title: FUZZY SMITH PREDICTOR FOR NONLINEAR PLANTS WITH TIME DELAY BASED ON PARALLEL DISTRIBUTED COMPENSATION.
Keywords: fuzzy Smith predictor, nonlinear plant, parallel distributed compensation, simulation, stability, time delay compensation.
Abstract: A method for the design of fuzzy Smith predictor (FSP) for a nonlinear plant with time delay is developed. The FSP is based on Takagi-Sugeno-Kang (TSK) plant model, comprised of linear local plants with significant time delays. Тhe principle of Parallel Distributed Compensation (PDC) is employed and the local linear controllers are designed as classical Smith predictors for the corresponding local linear plants aiming at compensation of their time delays. Lyapunov conditions for analysis of the global fuzzy system stability are suggested in the form of linear matrix inequalities. A FSP is designed for the control of the temperature in a laboratory furnace and the closed loop system is investigated via simulations.
