| 摘 要： | 提出了一种基于输出拟形的解耦控制器设计方法。设计过程中针对某型涡扇发动机双变量控制系统,首先选取2个理想的一阶环节形成2个独立控制回路,以其在各通路单独阶跃下的无耦合响应为拟形目标。以LQR控制器设计为例,采用遗传算法(GA)来优化LQR控制器的加权矩阵Q和R,使闭环控制系统在各控制回路单独阶跃下的输出与目标相一致,从而达到解耦的目的。通过优化算法,设计出的LQR控制器取得了良好的动、静态解耦效果。

| Abstract: | The decoupling controller design method based on the output shaping is presented in this paper.For a double variable control system of certain turbine-fan engine,two first order systems are selected to make two independent control paths.The responses of this two paths have no coupling.The step outputs of the two inde- pendent paths are assumed to be chosen to be the target outputs of the close-loop control system.Using the de- sign process of LQR controller as an example,the weighting matrixes Q and R of the LQR controller can be ob- tained through genetic algorithm(GA)optimization.Then the step output of the LQR close-loop control sys- tem designed by the optimal Q and R can be consistent with the target output.Through the optimization algo- rithm,the control system with the LQR controller gets very well dynamic and steady state decoupling perform- ance. |
