Empirical Mode Decomposition (EMD) is a decomposition algorithm which is used to analyze signal. In this paper, a new fault diagnosis approach, which is the EMD based on the optimization of noise reduction, is proposed for bearings. Firstly, the original signal is decomposed into a set of Intrinsic Mode Functions (IMFs) by EMD combined with Genetic Algorithm (GA) for reconstruction. Then effective...
In this paper, a method of fault estimation and fault tolerant control for networked control system (NCS) with transfer delay and process noise is presented. First, the networked control system is modeled as a multiple-input-multiple-output (MIMO) discrete-time system with transfer delays, process noise, and model uncertainties. Under this model and under some conditions, a fault estimation method...
