摘　　要：在此将鲁棒控制中的μ分析与综合方法应用到400 Hz单相航空电源系统中,该方法可以提高航空电源的动静态性能。首先在建立航空电源数学模型的基础上,将负载和变压器漏感作为不确定因素,利用μ分析和综合方法设计出一个鲁棒控制器,其次通过20 kW的实验验样机分别对整个系统进行了相关实验验证,结果表明：该鲁棒控制器仅用一个电压环就能使系统有很好的动静态性能和鲁棒性,稳态电压稳定在114.5-115.5 V,动态恢复时间在10ms以内。The method of μ analysis and synthesis method of robust control is applied to the 400 Hz single-phase aviation power supply system.The method can improve the dynamic and static performance of the power supply.Firstly on the foundation of establish the mathematical model of air power, the load and the leakage inductance of the transformer as uncertain factors, μ analysis and synthesis method are used to design the out a robust controller.Secondly, a 20 kW prototype respectively of the whole system is experimented.Experimental result shows that the designed robust controller only using a voltage loop can let the system has a good dynamic and static performance and robust performance,steady state voltage stability between the 114.5-115.5 V,dynamic recovery time is about 10 ms.
