Abstract :
A novel attitude control strategy for hydrofoil catamaran throughout its operating range has been proposed to overcome the drawback of the conventional linear quadratic regulator (LQR) strategy, via fuzzy model-based system in this paper. The Tagaki-Sugeno (T-S) fuzzy model equipped with parallel distributed compensation (PDC) scheme is first constructed. By means of Matlab LMI control toolbox, a common positive definite matrix is found to guarantee the global fuzzy system\´s stability of hydrofoil catamaran. Second, the nonlinear mathematical model for hydrofoil catamaran is established. After Jacobian linearization, the state-space model is proposed. Finally, based on hydrofoil catamaran "HB200B-A1", simulation researches demonstrate the reliability of the established nonlinear mathematical model and the effectiveness of our fuzzy controller.
