This work presents a novel linear algebra methodology able to adequately design the controller algorithm for an efficient trajectory tracking of a continuous stirred tank reactor (CSTR). The mathematical model of the CSTR is represented by a system of coupled nonlinear differential equations, which is then approximated through a discrete statement of the problem. The discrete model is reorganized as a system of linear equations, which is used to find out a simple solution for the optimal control actions. An advantage of the present approach is that both the condition of negligible tracking error and the calculation of control actions are obtained by solving a system of linear equations. A Monte Carlo method is used for tuning the controller adjustment parameters. The simulation results show a good performance of the proposed control law.
