Embodiment Construction
[0070] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0071] The purpose of the present invention is to provide a single-step predictive control anti-rolling method for a high-speed multi-hull ship, which can improve the longitudinal motion stability of the high-speed multi-hull ship.
[0072] A single-step predictive control anti-rolling method for a high-speed multi-hull ship, which specifically includes the following steps:
[0073] S1, establish the vertical motion model of the multihull coupling;
[0074] S2, mathematically transform the coupled vertical motion model to obtain a single-input single-output decoupled heave and pitch motion model;
[0075] S3, design a finite-time observer, estimate the coupling term of the multihull heave motion and pitch motion online, and obtain the anti-roll compensation amount;
[0076] S4, design a single-step predictive control law, and solve th...
