摘要
针对减摇鳍电液负载仿真台加载系统和减摇鳍驱动系统之间的耦合,设计了前馈补偿解耦控制器,以消除多余力。仿真结果表明,该方法对于消除多余力具有较好的效果,能满足系统加载的要求。在考虑伺服阀的动态特性时,该方法比采用结构不变性补偿原理的方法具有更好的补偿效果。
Contraposing the coupling of the electro-hydraulic load simulator of fin stabilizer between loading system and the driving system of fin stabilizer, a feed--forward compensation decoupling controller to eliminate surplus force was designed. According to the simulation results,this control method is effective in eliminating surplus force and can fulfil the loading requirements of system. Considering dynamic characteristics of the servo valve,this control method is more effective than that of the structure invariance compensation principle in eliminating surplus force.
