Control of a Benchmark CSTR Using Feedback Linearization

Abstract

Output regulation control for a CSTR benchmark problem is considered using a feedback linearization technique, where a linear control method is applied to the system for the purpose of maximizing the yield of a desired product at a specific operational temperature. Simulation results showed that the proposed feedback linearization-based controller strategy was successful in maintaining the desired product concentration at its set points, while maintaining the cooling jacket temperate fixed at all times, and the manipulated variables were maintained within their respective operational limits. The proposed feedback linearization-based controller provided very promising results, where it guaranteed a precise operation of the reactor with good performance in terms of a stable transition with no overshoot, and exhibited robustness by rejecting the tested disturbance in the form of a sinusoidal time variation in the reactant feed concentration.
