A comparative study for the boundary control of a reaction-diffusion process: MPC vs backstepping

Model-based Predictive and Backstepping controllers for a state coupled four-tank system with bounded control inputs: A comparative study

“…Different publications and approaches such as those presented in the previous paragraphs for every proposed control method as well as some comparative studies of these control approaches on other processes [19] and with other approaches [20] can be found in the literature, but until now (as far as the authors know), no comparative study between these control approaches in application on liquid level systems has been presented in the literature. This paper utilizes nonlinear Backstepping technique and NGPC approach on the nonlinear dynamics of a state-coupled, four-tank, liquid level system to develop controllers with trajectory tracking capabilities in the presence of inputs saturation.…”
