摘要/Abstract

摘要： 为了解决几何可调冲压发动机多变量耦合下的控制问题,设计了此发动机的混合灵敏度H∞鲁棒多变量控制器。在大偏离非线性动态模型基础上进行了仿真试验验证并与原单变量多回路控制器进行了对比,试验结果表明此多变量控制器可以有效地减小输出超调,提高了发动机的稳定裕度。 

Abstract: In order to solve the multi-variable control problem for variable geometry ramjet engine, the H∞ mixed-sensitivity robust multi-variable controller is designed. On the basis of large deviation nonlinear dynamic model, the simulation is scheduled to compare the performance for single-variable multi-loop controller. Simulation and experimental results show that this method has smaller pressure overshoot and larger stability margin.

Key words: Ramjet engine; Variable geometry; Multi-variable control; H∞ robust control
