Abstract :
This paper presents new, high-performance, nonlinear control laws for single-input single-output nonlinear processes with input constraints. Whether input constraints are present or not, each of these dynamic control laws minimizes the mismatch between the closed-loop output response and the nominal linear output response that the same control law induces when there are no constraints. The connections between the developed control laws and the modified internal model control are established. The superior performance of the derived control laws is demonstrated by an example of chemical reactor
