全浸式水翼艇纵向运动姿态解耦控制

Uncoupling Control for the Longitudinal Postures of Fully Submerged Hydrofoil

本文对全浸式水翼艇纵向运动姿态的解耦控制进行了研究。首先根据其数学模型进行了解耦,然后采用古典控制理论按SISO系统进行了动态设计,最后在数字计算机上对PCH水翼艇的纵向运动姿态在解耦与不解耦条件下的闭环控制系统进行了数字仿真和比较。结果表明:对于全浸式水翼艇纵向运动姿态采用解耦控制可获得令人满意的效果,且设计方法简单易行。

Uncoupling control for the longitudinal postures of fully submerged hydrofoil is studied in this paper.First,according to the mathematic model of the hydrofoil, uncoupling is carried out. Second,transient state adjustment is carried out as SISO system by means of the classical control theory. Final, digital simulation of the uncoupling and coupling control systems of the longitudinal posture of the hydrofoil is carried out in the computer, and the results of the simulation are compared.The results show:if uncoupling control is apl-lied on fully submerged hydrofoil,satisfactory result can be obtained, and this kind of method is simple and easy for realization.
