The purpose of this dissertation is to show the development and testing of an adaptive feedforward control of a ,wastewater neutralization, process. The adaptive controller is compared to a nonlinear proportional-integral-derivative (NPID) controller developed by Shinskey (1970). The process and controllers were simulated digitally.
