| 摘 要： | 为改善传统导弹姿控系统线性控制法的不足,用相平面法分析了直接力作用下导弹的姿态运动规律和气动力作用对直接力控制的影响,提出了一种综合控制精度、姿控发动机产品特性和推进剂消耗量等指标的直接力非线性控制方法,给出了控制模型。仿真结果表明,该法能在气动力作用或干扰无法忽略的条件下实现导弹姿控发动机的开关工作正常,保证精度及推进剂消耗最省,其控制精度与线性比例微分(PD)控制律相当。

| Abstract: | To improve the traditional linear control of the attitude control system for missile,a nonlinear control method using direct force based on the analysis of the attitude motion rule of a missile acted by direct force and the impact of aerodynamic force on direct force control with phase plane in this paper,which was integrated with control accuracy,production character of the attitude control motor and propellant consumption.The control law was presented.The simulation results showed that this method could realize the normal operation of open and off for the missile's attitude control motor,control accuracy and least propellant wastage.The control precision of the new method was similar with that of linear PD control law. |
