摘要
研究了一类可以抑制切换时刻输出跳跃的多模型切换控制器的设计问题。基于参数化特征结构配置结果及模型跟踪方法,设计了满足输出跟踪性能并使多模型系统中各闭环子系统渐近稳定的多模型切换控制律集合。充分利用了参数化特征结构配置方法提供的全部自由度,协调选取各子系统控制律中的参数来抑制切换时刻的输出跳跃。将本文提出的方法应用到某型倾斜转弯导弹自动驾驶仪设计中,仿真结果表明导弹的输出过载迅速准确跟踪制导指令,并且切换抖动得到有效抑制。
The problem of designing a switching controller for chattering attenuation in multi-model systems is considered. Based on the method of eigenstructure assignment and the model tracking theory, a set of multi-model switching controllers is designed to stabilize each subsystem and make the outputs of the closed-loop systems satisfying certain tracking performances. Output chattering is attenuated through selecting all the degrees of freedom provided by the method of eigenstructure assignment. A bank-to-turn ( BTT) missile autopilot is designed by using the proposed approach. Simulation results show the effect and validity of the proposed method in command tracking and switching chattering attenuations.
