Along with the development of sea national defense and ship industry , the electro - hydraulic load simulator of fin stabilizer with high performances is urgently demanded . because the electro - hydraulic load simulator of fin stabilizer - is a kind of typical passive electro - hydraulic force servo system , the large surplus force caused by strong disturbance of the fin stabilizer displacement seriously affects the static and dynamic performances of the electro - hydraulic load simulator 随着海军国防和船舶工业的发展,迫切需要高性能的船舶电液负载仿真台,但由于减摇鳍电液负载仿真台属于典型的被动式电液力伺服系统,其加载系统受减摇鳍的强位置干扰会产生强大的多余力,严重影响加载系统的动静态品质。
It is necessary to design robust controllers based on the normal plants so that the controlled systems have satisfactory properties by considering the existence of uncertainties . based on lyapunov stability theory , geometry theory for nonlinear systems , dissipative theory and etc , the robust hk control for uncertain nonlinear systems and the reliable h control problem of uncertain nonlinear systems are studied , and the control laws are proposed correspondingly for several typical nonlinear systems in this paper . the robust controller design methods are presented and the proposed method is applied to design the control system of lift feedback fin stabilizer by considering the linear model , nonlinear model and coupled nonlinear model of ship motions 本文研究了不确定非线性系统的鲁棒控制问题,以lyapunov稳定性理论、非线性系统几何理论、耗散理论等为基础,对非线性系统的鲁棒h _控制、非线性系统的鲁棒h _可靠控制进行了深入的研究,针对几类典型非线性系统,提出了相应的鲁棒控制方法,对于升力控制减摇鳍系统(本文中简称为力控鳍系统) ,考虑船舶运动的线性模型、非线性模型和非线性耦合运动模型,提出了相应的控制方法。
