基于开环补偿的飞机偏航角控制系统设计及仿真

飞机侧向姿态运动的有关侧向力、力矩具有较强耦合性,且基于副翼、方向舵对侧向运动实施控制,侧向运动这些特点必然导致侧向控制系统设计的复杂性。为设计飞机偏航角侧向姿态控制系统,首先,基于飞机侧向运动的动力学方程组,建立了飞机侧向姿态控制系统全面运动结构图;然后,在分析全面运动结构图基础上,基于开环补偿原理,设计了一种飞机偏航角侧向姿态控制系统,即通过引入交叉传动比,将滚转通道的γ信号引入偏航通道,通过调节来实现基本协调转弯的控制结构方案;最后,在Matlab平台下,对所设计的飞机偏航角侧向姿态控制系统进行了大量仿真研究。仿真结果显示,通过调节可减弱飞机滚转运动和偏航运动的耦合影响,基于开环补偿的飞机偏航角侧向姿态控制系统是合理可行的。

Design and Simulation of Aero Yaw Angle Movement Control System Based on Open Loop Compensatory

Because the relevant force and moment of aero lateral attitude movement are stronger hinge coupling, and aerolateral attitude movement is controled using aero ailerons and rudders, these characteristicses of aero lateral attitude move.ment inevitable cause design complexity of the lateral attitude movement control system. In order to design aero yaw anglemovement lateral attitude movement control system, firstly, lateral attitude control system general movement structure wereestablishmented based on dynamics equation set of lateral attitude movement. Secondly, the overall movement structure di.agram was analyzed, and a kind of aero yaw angle movement lateral attitude movement control system was designed basedon open loop control principle. Namely, this was the control structure project that could realizate the basic concerted turncontrol by regulating hinge transfer ratio which the roll signal was imported into yaw channels. Lastly, under the Matlabplatform, a great deal of simulation researches were done to designed aero yaw angle movement lateral attitude movementcontrol system. Simulation results showed that the cross linking effect of roll channels and yaw channels was weaken byregulating. Desgined aero yaw angle movement lateral attitude movement control system was reasonable and feasible.
