针对滑翔制导炸弹,提出了一种变增益鲁棒控制器设计方法.通过将作战空域划分为几个小空域,并在其中一边界点对线性化后的系统,采用双回路鲁棒设计方法,设计满足系统性能和动态性能的鲁棒控制器.然后在各个边界点,采用插值方法将控制器内回路设计成与高度和速度相关的连续变增益控制回路,使内回路控制参数随着滑翔制导炸弹的飞行状态变化而变化,从而提高系统的性能.仿真结果表明,设计的控制器具有良好的时域响应性能,可以控制滑翔制导炸弹在大范围飞行过程中稳定,获得了满意的控制效果.
Aiming at the gliding guidance bombs, a variable gain robust controller design method is proposed. By dividing the combat airspace into several small airspaces, and using the double loop robust design method, A robust controller is designed to meet the system performance and dynamic performance.At the boundary point, interpolation is used to design the inner loop of the controller into a continuous variable-gain control loop which is related to height and velocity, and the inner loop control parameters are guided by the gliding guidance The flight state of the bombs changes, so as to improve the performance of the system.The simulation results show that the designed controller has a good time-domain response performance, can control gliding guided bombs in a wide range of flight stability and obtain satisfactory control effect.
