ABSTRACT

The goal of this paper is to describe a linearizing feedback adaptive control structure which guarantees high quality regulation of the output error in the face of unknown parameters. The effectiveness of this control structure is demonstrated on a continuous stirred tank reactor in two instances. The first is when there is full state feedback and the second when only temperature measurements are available. In the latter a nonlinear observer is constructed to infer conversion. In both cases conditions for asymptotic stability are presented and discussed.
