航空发动机非理想解耦自适应控制
Incompletely Decoupled Adaptive Control in Aeroengine System
-
摘要: 本文对航空发动机的双变量控制方法进行了研究, 提出了一种非理想解耦自适应控制方法, 各子系统之间部分残余的相互耦合和非线性影响就通过自适应律本身的鲁棒性来解决。仿真结果表明该控制系统实现了解耦控制, 对发动机模型参数在大范围内的变化均有良好的控制效果。Abstract: An incompletely decoupled model reference adaptive control method is proposed for aeroengine binary control system.A new adaptive control method is applied to every incompletely decoupled subsystem,then remains of coupling and nonlinear influence can be resolved by adaptive principle robustness.This binary decoupled adaptive controller can diminish the coupling gradually and has excellent robustness to model uncertainty and external disturbances.Simulation results demonstrate the effectiveness of the incompletely decoupled adaptive controller.
