| Abstract: | Aiming at the difficulty of system identification modeling and fault diagnosis for nonlinear systems,a identification modeling system and a fault diagnosis system are designed for nonlinear systems,respectively,by using support vector regression (SVR) . Simulation of one nonlinear system is carried out as an example. The SVR identification model of the nonlinear system is established. Three typical fault simulation tests are carried out based on the SVR identification model. The simulation results show that... |
