Abstract

In this work the inverse model based temperature control of a batch chemical reactor is presented. The controller combines feed-forward and feedback elements. The feed-forward part is the constrained direct inverse, while multiple feedback structures are studied.

Since we have a model with good correspondence with the physical system, the inverse of it can produce the manipulated variable. The feedback is needed to eliminate the effect of modeling errors that is especially important in steady-state. For the compensation ...
