摘要
为提高拦截器姿控系统的控制精度,在研究常值推力姿控发动机的脉冲调制方式的基础上,建立姿控发动机的脉冲推力模型,重点设计动能拦截器基于非线性开关控制的姿控发动机控制律,并通过典型角度稳定跟踪过程验证控制律。仿真结果表明:姿控系统能够稳定地高精度跟踪目标,所设计的姿控系统具有有效性。
In order to improve the control accuracy of attitude control system of interceptor,pulse modulation of constant thrust thrusters was investigated,and then built thrust model of the impulse attitude control thruster.Emphasis on altitude thrusters control law design of dynamic interceptor based on non-linear switch control,then verify the control law by the typical angle stable tracing procedure.The simulation results show that the altitude control system can stably trace target in high precision,and the altitude control system is effective.
