An Industrial Dead-Time Compensating PI Controller
Forskningsoutput: Tidskriftsbidrag › Artikel i vetenskaplig tidskrift
An industrial PI controller with dead-time compensation is presented. The advantage of the new controller compared with other dead-time compensating controllers is that it contains only three adjustable parameters; the gain, the integral time, and the dead time. The simple parametrization is obtained by calculating the process model needed for the dead-time compensation from the controller parameters provided by the user. The controller is also suited to processes with varying dead times.
