【Abstract】 Quasi-keyhole arc welding process is a typical nonlinear system. In order to obtain the model of quasi-keyhole arc weld-ing process, this paper uses the least square method in the identification. Simulation results indicate that the least square method is an effective tool for nonlinear system identification.更多还原
