摘　　要：建立了风能转换系统传动部分的故障数学模型,并且在未知干扰情况下构造了自适应故障观测器,用以检测风能转换系统传动部分的故障,并对该故障进行自适应估计。设计了主动容错控制器来保证发生故障时风能转换系统传动部分的稳定性以及可靠运行,并给出各部分详细的稳定性证明。通过对主传动链不同故障类型的仿真,表明了自适应故障诊断及主动容错控制方法的有效性和可行性。The fault mathematical model of the transmission of wind energy conversion system is established, and adaptive fault diagnosis observer is constructed in the presence of unknown disturbance, it can detect the faults of the system, and adaptive estimate this fault. Then, based on fault diagnosis observer, an initiative tolerant controller is designed to ensure the stability of the transmission of wind energy conversion system in case of the fault. The detall proof of stability for the system is given. The simulation results of different fault types of maln transmission chaln show the effectiveness and feasibility of adaptive fault diagnosis and initiative tolerant methods.
