【摘要】：船舶在海上航行時(shí)受到海風(fēng)、海浪和海流等環(huán)境擾動(dòng)作用,這造成在不同航速下船舶動(dòng)力學(xué)模型的參數(shù)不確定性,本文對(duì)船舶本體運(yùn)動(dòng)和風(fēng)浪流干擾進(jìn)行建模,提出一種基于分?jǐn)?shù)階PI~λD~μ的抑制風(fēng)浪干擾的的航向控制算法,并與傳統(tǒng)PID算法進(jìn)行對(duì)比,針對(duì)某型船舶動(dòng)力學(xué)模型在6級(jí)海風(fēng)和5級(jí)海浪海況下進(jìn)行對(duì)比數(shù)字仿真。仿真結(jié)果表明,該算法在不同航速下具有較好的控制品質(zhì)和魯棒性,對(duì)風(fēng)浪干擾具有良好的適應(yīng)性,可應(yīng)用于船舶的航向控制,易于工程實(shí)現(xiàn)。
[Abstract]:Ships are disturbed by sea wind, waves and currents, which lead to the uncertainty of ship dynamics model at different speeds. In this paper, the ship body motion and wind current disturbance are modeled. A course control algorithm based on fractional-order PI~ 位 D ~ 渭 is proposed to suppress wind and wave interference. Compared with the traditional PID algorithm, the dynamic model of a ship is simulated under the sea conditions of 6 and 5 degrees of sea wind. The simulation results show that the algorithm has better control quality and robustness at different speeds and has good adaptability to wind and wave disturbance. It can be applied to ship heading control and is easy to be realized in engineering.
