Abstract: |
The principle and procedure for identification of the linear constant system by the correlation method are discussed.An appropriate experimental set-up for identification with the L-series as the test signals and the welding current as thc controlled object is introduced.A suitable mathematical model is given for the ZX7-400S SCR-inverter are welding power source.The model is verified by testing and computer simulation. |
Key words: identification correlation inverter |
