摘要

动能杀伤飞行器进入末制导阶段时，具有非线性、强耦合和多输入多输出的特点。为了解决这些问题，采用比例微分(PD)控制律对每个通道设计控制器，然后引入反馈线性化方法将耦合系统发展为独立的子系统。针对姿态控制推力器的开/关信号，采用脉宽脉频调制器对反馈线性化输出进行调节。仿真和结果表明本文所采用的控制策略是有效的。

A study on feedback linearization for kinetic kill vehicle attitude control system

When the kinetic kill vehicle (KKV) enters into terminal guidance, the characteristics of the KKV are nonlinearity, strong-coupling and MIMO. In order to solve these problems, the proportion differential (PD) control law is adopted to design controller for each channel, then the method of feedback linearization is introduced to develop the coupled system into independent subsystems. For the sake of the on/off signals for the attitude control thrusters, the pulse-width pulse-frequency (PWPF) modulator is utilized to adjust the output of the feedback linearization. The simulations and results illustrate the control strategies employed in this note are effective.
