) Abstract: The article talks of a way of joint model identification for the process control
It combines the direct identification of continuous model which base on step response, and method of least squares identification which base on M sequence
The initial delay time can be obtained from the continuous identification, and it will be used in the least squares identification to get the final delay time and model parameters which make the residual error smallest
The effectiveness of the method has been demonstrated through a number of simulation examples
