ABSTRACT:
In the measurement of a variable process parameter and control of the process in response thereto, the time derivative of a second order or higher lagged process measurement signal is utilized to provide predictive capability in generating a process variable signal, in generating a process control signal, and in controlling the process in response to the measured parameter. The system is particularly well adapted to control of a non-self-regulating process.
