Study on generalized predictive control for π type rudder pitching stabilization

The state space mathematical model was proposed for π type rudder pitching stabilization. Based on generalized predictive control theory with suitable simplification, an output multi-step predictive and generalized predictive control law for π type rudder pitching stabilization was developed. Using linear Kalman filter to estimate system states with white-noise interference, for submerged Hydrofoil Craft, a mathematical simulation was conducted. The simulations show that the proposed method is effective with good parameter robustness. The good control effect of pitching stabilization is achieved.
