摘要
基于状态观测器的故障检测诊断方法可很好地解决某些可测性差的系统故障检测诊断问题。然而,观测器的实现困难严重影响了此方法的应用。提出了一种MATLAB实现全维状态观测器的算法,并以二阶PID电路的状态观测器实现为实例仿真,结果证明了该方法的有效性。
The state observer-based fault diagnosis method can solve some of faults check and diagnosis of bad measurability system well, while the realize difficulty of state observer affect it＇ s applying seriously. A accomplish algorithm of full-dimension state observer by MATLAB is advanced, and one of two-order PID circuits is used as an example. The simulation results prove the validity of this algorithm.
