摘要
采用非相似余度设计思想,建立了无人机横侧向控制系统。对典型故障模式的控制系统进行了分析,结果表明该系统不但具有较好的控制品质,而且对单通道控制故障引起的干扰具有较好的抑制能力,可有效解决副翼故障可能导致的飞行事故问题,从而提高系统的可靠性。
Using the traditional coordination control configure for UAV, it is inadequate by closing an aileron channel in order to get rid of flying security-hidden trouble caused by a fault aileron. At the same time the lateral-direction control is unstable. With the method of dissimilar redundant design, this paper put forwards a lateral direction control system of UAV. From simulation results, this system not only has fine flight control qualities but also has good ability to restrain the disturbance caused by a single channel. This system can solve the flying accident when an aileron channel is in trouble, furthermore it can improve the reliability and security of the flight system.
