摘　　要：针对波音737-300飞机飞行模拟机操纵负荷系统,介绍了操纵负荷液压伺服系统的机械结构和工作原理,建立了操纵负荷力加载系统的数学模型并用方框图表示,分析了多余力产生机理,采用以位置信息作为前馈补偿进行多余力的抑制。仿真结果从理论上证明了前馈补偿方案可以很好地解决多余力带来的干扰,实验结果也证明了该方案的有效性和可行性。The mechanical structure and operating principle of the control loading system of the Boeing 737-300 flight simulator was introduced, a mathematical model of the control loading system was founded and was expressed by means of block diagram. The characteristics of the extra force were studied. A method of position feedforward compensating the extra force based on the principle of structure invariance was presented. The result of the simulation shows theoretically that the feedforward compensating can reduce the interference caused by the extra force effectively. The feasibility and validity of the method were proved by experiments.
