摘要: 将给定特征点的倾斜转弯(BTT)导弹俯仰偏航通道动力学模型视为可依滚转角速度变化而进行切换的线性切换系统.针对每个独立子系统采用特征结构配置方法和前馈补偿方法设计参考模型和控制律,以滚转角速度为决策变量,根据其量值在各控制器间进行切换.控制器集合可以有效抑制滚转角速度大幅变化产生的模型不确定性,具有较好的鲁棒性.采用公共Lyapunov函数方法,以线性矩阵不等式为形式,推导了能够保证闭环切换系统在滚转角速度变化范围内一致有界的充分条件.

Abstract: The mixed pitchyaw channel dynamic model of banktoturn (BTT) missile at one operating point was described as a linear switched system switched as the roll angle rate changes. The reference model and control law of each subsystem were designed based on the eigenstructure assignment method and the feedforward method. The different controllers can be fast switched according to the switching law determined by the roll angle rate of missile. Thus the set of different controllers can restrain the model uncertainties caused by the rapid change of roll angle rate, which means it has better robustness. To ensure the uniform boundedness of the closedloop switched system within the whole varying range of roll angle rate, a sufficient condition in the form of linear matrix inequations was deduced using the common Lyapunov function method.
