现代飞机越来越多地采用电传飞控技术,相较机械系统具有便于多功能综合、易于实现主动控制的优势。舵回路作为电传飞控系统的重要组成部分,用于执行控制指令实现舵面偏转,其控制特性对飞行品质影响至关重要。就某民机方向舵伺服作动系统进行频域特性的分析研究,建立数学模型,仿真分析其频域特性,并通过铁鸟综合实验台验证仿真结果。
More and more modern aircraft using fly-by-wire technology, compared with the mechanical system has the advantages of easy to multi-function synthesis, easy to achieve active control. As an important part of the fly-by-wire flight control system, the rudder loop is used to execute the control commands to achieve the deflection of the rudder surface. The control characteristics of the rudder loop are of crucial importance to the flight quality. The frequency domain characteristic analysis and research of a civil aircraft rudder servo actuation system is established. The mathematical model is established, the frequency domain characteristics are simulated and analyzed, and the simulation results are verified by the comprehensive experimental platform of the Aerobatics.
