摘要:

建立了敏捷导弹的动力学模型,引入力和力矩放大因子来描述横向喷流的干扰作用。针对直接力/气动力复合控制模型,提出了一种基于模型参考的自适应控制分配方法。引入了加权分配策略,该方法将复合控制系统分解为气动力和直接力两个子系统,使设计问题得到简化。采用遗传算法(genetic algorithm, GA)对加权因子进行了多目标优化设计。仿真结果表明,所设计的复合控制系统能够快速稳定地跟踪输入指令,解决了直接力和气动力子系统的加速度分配问题。

Abstract:

The dynamic model of agile missiles is developed. The force and torque amplification factors are used to describe the influence of jet interaction for the missile. For the direct force / aerodynamic compound control model, adaptive control allocation based on model reference is presented. In order to simplify the design, the strategy of weighted allocation is introduced, which can make the hybrid control system decompose into two subsystems, aerodynamics subsystem and direct force subsystem, respectively. The weighting factors are selected by using a genetic algorithm (GA) to optimize the multi objective cost function. The simulation results show that the designed blended control system can track the input command rapidly and implement the acceleration allocation between direct force and aerodynamic force.
