【摘要】 针对机载布撒器,提出了一种连续变增益鲁棒控制器的设计方法。这种方法将作战空域划分为几个小的区域,在边界点对线性化后的系统利用H∞混合灵敏度方法设计满足系统H∞性能和动态性能要求的鲁棒控制器,然后将控制器拟合成与布撒器飞行高度和速度相关的连续变增益控制器。随着布撒器飞行状态的变化,所设计的变增益控制器能够适应系统状态的快速变化,克服了传统变增益控制器的不足,具有较好的系统性能。仿真结果验证了此控制器的有效性。更多还原

【Abstract】 An approach to designing continuous gain scheduled robust controllers for airborne dispenser has been presented in this paper.The approach separates the fighting region into several small parts.By linearizing the system at boundary points and utilizing H∞ mixed sensitivity method,we design robust controllers satisfying H∞ performance and dynamic qualities at every part.Then the controllers are fitted to a continuous gain scheduled controller which is correlated with the altitude and velocity of the dispenser.With the changes of the flying states of the dispenser,the controller can adapt to the fast varying states of the system,which overcomes limitations of the conventional gain scheduling controllers,and has preferable performance.Simulation results prove the effectiveness of the controller.更多还原
