Abstract :
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.
