摘　　要：针对现阶段工程实践的需求,对飞行器舵机电动伺服加载系统进行了理论上的分析和研究,建立了电动伺服加载系统的数学模型,对影响其动态控制系统性能指标的多余力矩进行了分析,引入了速度和加速度补偿以减小多余力矩、提高加载系统性能。进行了相关的数字仿真,最后给出了可行性分析。Servo loading system (SLS) is an important simulation system in hardware-in-loop flight simulation laboratory, which can simulate aerodynamic loads acting on the rudders of aircraft. To meet the demands to develop the current EHSLS (Electro-hydraulic servo loading system) into MSLS (Motor servo loading system) and to improve the systems performances, some basic technical problems about MSLS in theory and application are studied in this paper. First, the MSLS?s mathematical model is established. Then, digital simulation and analyses about the system are carried out. By analyzing the simulation results about the system, the conclusions are reached that adding of speed compensation and acceleration compensation in MSLS can further improve the systems performances to some extent so as to satisfy the requirements of applications.
