Abstract
A simple mechanism that renders robustness to a nonlinear controller designed using an internal-model control (IMC) strategy is presented. A comparative study between this and the conventional IMC strategy for controlling the pH of a strong acid—strong base solution shows five orders of magnitude improvement in the extent of sampling time that can be tolerated. The simulations also suggest speedier recovery of system to the set point in the presence of load disturbances and modeling errors.
