Observer-Based Control of a Continuous Stirred Tank Reactor with Recycle Time-Delay * *This paper is supported by the University of L'Aquila ex 60% and Ph.D. school funds

This paper proposes the design of an observer-based control law for a continuous stirred tank reactor with recycle time-delay. Recent results on differential geometry for nonlinear time-delay systems are used. The many performed simulations show the high performance of the proposed control law.
