“…Since Controller 2 shows a better performance compared to controller 1 according to the relative quantitative and qualitative comparisons made in Bejarano et al (2017a), comparison figures are only shown for comparison of RMPC with Controller 2, while the quantitative comparisons with both controllers are shown in Table 2. Table 2, the proposed controller significantly outperforms both discrete decentralized PID and multi-variable PID as it improves the overall index, J, by 80% compared to former and by 70% compared to latter.…”

“…Due to these benefits, a RIOTS based model predictive control enhanced by a conditional integral control is proposed to control the refrigeration system introduced in PID2018 benchmark problem (Bejarano et al (2017a)) and the results are compared with the results shown in the main document. The rest of this paper is organized as follows.…”

This paper presents a multi-variable Model Predictive Control (MPC) based controller for the one-staged refrigeration cycle model described in the PID2018 Benchmark Challenge. This model represents a two-input, two-output system with strong nonlinearities and high coupling between its variables. A general purpose optimal control problem (OCP) solver Matlab toolbox called RIOTS is used as the OCP solver for the proposed MPC scheme which allows for straightforward implementation of the method and for solving a wide range of constrained linear and nonlinear optimal control problems. A conditional integral (CI) compensator is embedded in the controller to compensate for the small steady state errors. This method shows significant improvements in performance compared to both discrete decentralized control (C1) and multi-variable PID controller (C2) originally given in PID2018 Benchmark Challenge as a baseline. Our solution is introduced in detail in this paper and our final results using the overall relative index, J, are 0.2 over C1 and 0.3 over C2, respectively. In other words, we achieved 80% improvement over C1 and 70% improvement over C2. We expect to achieve further improvements when some optimized searching efforts are used for MPC and CI parameter tuning.
