| 中文摘要 |
| 提出了一种采用自适应技术来实现对动态系统中非线性执行器故障诊断的新方法.执行器的故障可看成是由其参数的非期望变化变化所导致.本文构造了一种自适应观测器，由于该观测器的自适应部分包括了参数估计，故障诊断可由参数估计直接获得.文中证明了算法的收敛性，并通过一个仿真实例说明了算法的适应性. |
| 英文摘要 |
| This short paper presents a novel solution to fault diagnosis of nonlinear in known deterministic dynamic systems.The actuator is characterized by a parameter vector whose unexpected changes are regarded as the faults in the actuator.A nonlinear adaptive observer is constructed which incorporates the estimation of the parameter vector.Using the well parameter vector is obtained and is shown to be able to generate a desired diagnosis.An example is included in order to demonstrate the use of the proposed approach. |
