Abstract
Systems and methods are provided for controlling chemical production and/or petroleum processing reaction systems to allow for improved control of control variables relative to desired set points. The improved control can be achieved by use of a modified proportional-integral-derivative (PID) controller or a similar type of controller that includes dynamic tuning logic. The modified PID controller can be operated using different coefficients based on the relative values of a control variable and a reasonable progress curve determined based on the values of the control variable.
