摘要
为了解决在被控对象和控制器同时摄动时飞行控制系统的设计问题,提出了非脆弱μ综合鲁棒控制系统设计方法。通过数学模型的转换,将控制器的摄动转化为被控对象的摄动,解决了一类常规的鲁棒飞行控制性能设计不能保证控制器摄动时系统具有较好性能的问题。以某推力矢量飞机侧向运动为例,对其进行了非脆弱μ综合设计并做了数字仿真。仿真结果表明,本文提出的方法具有良好的鲁棒性和可行性。
The method of the non-fragileμ synthesis robust control was proposed for the design of common flight control system with the perturbations of the controlled members and the controllers. The perturbations of the controllers can be converted into those of the controlled members by the transformation of the mathematical model, so it can be used to solve the robustness problems of the perturbations of the controllers, which can＇t be done by conventional robust flight control performance designs. The design of non-fragileμ synthesis and digital simulation for a lateral motion of a thrust vector aircraft were given. The simulation results show that the method is excellent robust and effective.
