超燃冲压发动机PID解耦控制设计

针对超燃冲压发动机控制通道间的强耦合性及其控制过程的快速性要求,研究设计了超燃冲压发动机分路式PID解耦控制器;该方法采用零极点配置技术,设计了稳定的前馈补偿解耦器,并利用此解耦器对超燃冲压发动机模型进行解耦;对解耦后的控制对象设计了每个控制回路的PID控制器,实现分路式控制;仿真结果表明,所设计的解耦器比静态解耦器更能有效地解决发动机耦合问题,控制器控制效果满足控制精度和快速性要求;该方法简单实用对超燃冲压发动机的控制器设计有借鉴意义。

PID Decoupling Control of Scramjet

For the strong coupling of scramjet control channels and the requirement of fast control process,in this paper,a steady feed-forward compensation decoupler was used to decouple the scramjet model,which is designed by pole-zero placement method.Then PID controllers were designed for the decoupled model and achieved decentralized control.Simulation results show that the decoupler is more effective than static decoupler to solve the coupled problem of engine,and control effect meets the requirement of control ...
