摘要
简要介绍了运用逆系统方法设计空空导弹跟踪控制器的原理,分析了系统设计的反馈线性化控制律和状态反馈解耦条件,并建立了控制器的Simulink仿真模型。仿真结果表明,通过对弹道坐标系下导弹的纵向和法向过载实施控制,可使导弹的速度、偏航角和俯仰角输出信息以较高的精度快速跟踪预期指令,所设计的控制器具有一定的抗干扰能力,从而验证了控制器设计的合理性和有效性。
The principle of the inverse system method to design a tracking controller for an air-to-air missile system is described briefly. Then, the control law of feedback linearization and the conditions of decoupling control caused by state feedback are analyzed, and the simulation models for all tracking controller are designed with the simulink toolbox in Matlab 6.5. The simulation results show that it is accurate and fast to realize the tracking control to the reference command of missile's velocity and position angles by controlling longitudinal and normal overloads, and the controller possesses anti-interference characteristic, so the designed controller is reasonable and effective.
