摘要
针对大气层内滚转角速度稳定动能拦截器具有反应快速、耦合性强等特点,本文首先分析了传统的小扰动法设计姿控系统的优缺点,然后提出了基于极点区域配置的变增益控制系统设计方法。该方法通过在整个参数空间寻求单一李亚普诺夫函数来保证系统的全局稳定,与小扰法相比,它不仅可保证理论上的稳定,而且离散计算量小。最后的仿真表明,基于该方法设计的控制器具有良好的控制性能。
Considering that the atmospheric kinetic interceptor with invariable rolling rate has quick response and strong couphng, tiffs paper firstly analyzes the advantage and disadvantage of the classic design method of the control system, and then it proposes the gain scheduling method based on the regional pole placement, which finds a Lyapunov function in the whole parameter space to guarantee system stability. Compared with the classic method, the new method is not only stable theoretieally, but also convenient in calculation. Simulation results show that controller based on the method which be proposed in this paper has good performance.
