基于μ综合的空-空导弹驾驶仪增益调度方法研究

摘要

为克服单一μ综合控制器实现空-空导弹驾驶仪全包线控制的保守性,提出了基于动压调度变量插值的空-空导弹驾驶仪μ综合控制器调度方案;分析了基于控制器输出信号插值的方案,避免控制器状态空间实现矩阵插值中对控制器的阶次约束,具有更好的灵活性,通过仿真结果验证改进方案可保证调度过程中状态变换的平滑性并有效地保证全包线飞行时弹体鲁棒镇定.%To overcome the conservative of one singleμ-synthesis controller to control the full envelop,dynamic pressure was employed as scheduling variable to schedule theμ-synthesis controller of the sample air-to-air missile autopilot based on interpolation method.A new scheme is presented based on interpolation control signals between design points,which avoids the restriction of controllers' order and provides more flexible.It was proved by simulation that the new scheme achieves a smooth transition between controllers and ensures missile robust stabilization of the full envelop.
