In this paper, an adaption mechanism for control signal weighting
factor in Generalized Predictive Control (GPC) Technique has been
build. This factor changes according to the amplitude of the
measured disturbance affecting the acid influent in pH
Neutralization
process. The main purpose of this adaption is to
reduce rigorousness and severity of the manipulated variable of
alkaline flow actuator, which result in protecting the actuator from
damage, so lengthen its life and shrinking the maintenance costs.
The efficiency of the Adaption was observed by calculating the
integral of the absolute value of the error (IAE) and the integral of
absolute derivative signal (IADS) from simulation results.
