摘要
为了研究干扰对固定鸭舵制动精度的影响,介绍了双环PID制动控制原理和算法结构,分析了各项干扰的影响机理和表现形式,基于仿真实验对各干扰项对制动产生的影响进行了分析。结果表明:各项干扰对制动角的稳态均值影响不大,但会不同程度地加剧固定鸭舵的抖振。其中,滚转角测量误差会引起固定鸭舵的剧烈抖振。研究为制动控制算法的优化提供了依据。
In order to study fixed canard braking precision interferences,the double-loop PID braking control algorithm is introduced,and the influence mechanism and forms of interference is analyzed,influence on braking precision caused by various interference are analyzed based on the simulation results. The results show that：all kind of interferences have little effect on steady-state mean angle,but increase fixed canard buffeting at different levels. Among the interferences,the roll angle measurement error cause violent buffeting of fixed canard. This study provides the basis for the optimization of the brake control algorithm.
