| Abstract: | In order to improve the control accuracy of attitude control system of interceptor, pulse modulation ofconstant thrust thrusters was investigated, and then built thrust model of the impulse attitude control thruster. Emphasis onaltitude thrusters control law design of dynamic interceptor based on non-linear switch control, then verify the control lawby the typical angle stable tracing procedure. The simulation results show that the altitude control system can stably tracetarget in high precision, and the altitude control system is effective. |
