摘要
本文叙述了对线性定常系统进行相关辨识的原理和方法;介绍了以L序列为试验信号、焊接电流为被控量进行动态模型辨识的试验系统;建立了ZX7-400S型可控硅逆变式弧焊电源动态过程的数学模型;并通过试验和计算机仿真,验证了该模型的准确性。
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.
