This work shows that kinetic information is not needed to estimate states (compositions) and control continuous stirred tank reactors (CSTRs). An asymptotic observer is developed using reaction invariants to provide on-line estimates of unmeasured compositions. The estimates are used in a feedback controller, based on inventory control theory, to control compositions and reactor temperature. The dynamics of the reaction system are reduced using reaction variants and invariants. The reaction rates are estimated through differentiation of reaction variants, such that no kinetic information is required. An example of a serial reaction in a CSTR illustrates the theoretical results and the performance of the proposed adaptive control approach.
