建立了控制飞行器舵面的电液伺服系统的质量弹簧物理模型,辨识了特性参数,推导出伺服机构数学模型。采用电子动压反馈的位置闭环控制算法,通过仿真分析和样机带载试验,表明控制算法有效,能有效提高系统的动态特性。

A spring-mass physical model is proposed for vehicle rudders. The characteristic parameters are identified and the corresponding mathematical model for servo-mechanisms is derived. The servo-mechanism's control algorithm is studied using the digital DPF method. Then, simulation analysis and trial experiments are completed. The result shows that the digital DPF algorithm is effective, it effectively improve the dynamic characteristics of the system.
