摘要: 研究航空发动机多变量鲁棒控制器的设计方法。以某型涡轮喷气发动机为对象, 利用差分法得到发动机的小偏离状态空间模型, 计算了多种工况下的模型参数。利用LQG/LTR方法设计了发动机双变量鲁棒控制器, 研究了该控制系统的指令跟踪、解耦、干扰抑制等性能。Abstract: This paper researches the design methodology for multivariable robust controller of aero-engine.A small-divergence state space model for a given jet aero-engine has been established with the difference method.The Linear Quadratic Gaussian with Loop Transfer Recovery (LQG/LTR) method has been used to design a BIBO robust controller for the engine.The functions of the controller such as command following,decoupling and disturbance rejection have been considered.It is demonstrated that the LQG/LTR controller has excellent robustness for the uncertainty of the plant model.
