摘　　要：为有效抑制多余力对系统的伺服精度、动态性能和稳定性等指标的影响,提出PID+前馈补偿复合控制策略的设计思想。阐述电动操纵负荷系统的组成及工作原理,通过对系统的模型建立及仿真分析,深入了解多余力产生的机理及对系统的影响,并以俯仰通道为例,采用阶跃响应和正弦响应进行测试验证。结果表明,该控制策略能有效抑制多余力影响,提高电动操纵负荷系统的力感跟踪精度。In order to eliminate the extraneous force of the system and enhance the servo accuracy, dynamic capability and stability, put forward the PID ＆ IMC complex control method. Introduce the structure and working principles of the electric control loading system. Analyze the mechanism of production of extraneous force by setting up the mathematic model and simulating it, and to pitch channel, for example, using step response and sinusoidal response to test validation. The results indicate that the complex control method can lower the influence of extra force and enhancer tracing capability of the system.
