摘要： 针对传统非线性系统故障诊断方法中存在的线性化误差、滤波发散等问题,对一类含有测量噪声及执行器时变故障的非线性系统研究一类新的故障诊断方法。通过将系统的非线性动态及故障扩张为一新的状态,构造一种可用于故障诊断的扩张状态滤波器,并在此基础上推证出增广系统渐进稳定的充分条件,给出具有鲁棒H∞性能的故障诊断滤波器设计方法,同时借助于原系统中已知的非线性动态,对滤波后的新扩张状态进行故障分离,实现对故障的滤波及诊断。用该方法对具有测量噪声的典型非线性系统Van der pol振荡器,在分别发生恒值和时变故障情形下进行仿真研究。结果表明,所提方法能较好地解决含噪非线性系统的滤波及故障诊断问题。
Abstract: Aiming at the problem of the linearization error and filtering divergence for traditional fault diagnosis method of nonlinear system, a new fault diagnosis method was studied for a class nonlinear system with the measurement noise and actuator fault of time-varying. A new extended state including the nonlinear dynamic and fault of the system was constructed, and a class of the filter containing expansion stateis was constructed for fault diagnosis. The sufficient conditions of the augmented system were presented, meanwhile, the design method of the fault diagnosis filter with the robust H∞ performance was given. And the filter and diagnosis of the fault could be implemented by the fault isolation for the new extended state, among the known nonlinear dynamic of the original system. Based on the Van der pol oscillator that was typical nonlinear system with measurement noise, the simulation study for the constant value and time-varying failure condition was performed. The results showed that the proposed method could better solve noise filtering and the fault diagnosis problem of nonlinear systems
