ABSTRACT:
A system for controlling a process system with a process system gain and dead time of which its transfer function includes a gain term element corresponding to the process system gain and a dead time term element corresponding to the dead time, subject to an external disturbance, by adjusting a control variable output by the process system to a target value according to a manipulated variable output by a controller performing at least proportional and integral control operations based on a deviation between the control variable and the target value. The system includes dead time compensation unit, connected to the controller, including a system model unit having a system transfer function approximative to the transfer function of the process system and a model unit having a model transfer function resulting from eliminating the dead time term element from the system transfer function, for outputting a compensation output signal to compensate the dead time, and gain adjustment unit, connected to the dead time compensation means, for adjusting a gain of the system model unit to the process system gain according to the variation in the process system gain of the process system.
