摘要 针对一类非线性系统,研究基于自适应观测器的故障估计问题.设计了保证诊断系统稳定的实现故障估计的自适应调节律,并通过H∞跟踪性能,分析了调节律中的参数对故障估计精度的影响.数值仿真验证了该方法的有效性. Fault estimation based on adaptive observer is studied for a class of nonlinear systems. An adaptive fault updating law is designed to guarantee the stability of the diagnosis system, and the effects of parameters in adaptive updating law on fault estimation accuracy are discussed based on H∞ tracking performance. By simulation, the comparison is made using different updating laws and the result shows the correctness of the obtained results.
