Coupled multiple-tank systems are crucial for various industrial applications due to their unique uses, but the liquid level control for the coupled two-tank multi-input multi-output (MIMO) system is challenging. This paper proposes a novel anti-disturbance control strategy, utilizing a nonlinear composite hierarchical anti-disturbance predictive control (CHADPC) approach. The proposed method includes a model-based explicit nonlinear model predictive controller (ENMPC) and a nonlinear disturbance observer (DO) to estimate the disturbances, achieving effective control of liquid level.
Coupled multiple-tank systems are very important for a wide range of industrial applications due to their unique uses. However, the liquid level control for the coupled two-tank multi-input multi-output (MIMO) system is quite challenging because it has strong nonlinearity and coupling, and it is susceptible to multiple external disturbances. For this process, this paper proposes a novel anti-disturbance control strategy consisting on a nonlinear composite hierarchical anti-disturbance predictive control (CHADPC). First, a model-based explicit nonlinear model predictive controller (ENMPC) is designed assuming that all disturbances are measurable and its global exponential stability is proved. Then, a nonlinear disturbance observer (DO) is designed to estimate the lumped disturbances. The composite controller handling the estimated disturbances is then proposed. Finally, simulation and experimental tracking control tests under perturbations and comparisons with recently reported works have been carried out to highlight the promising performance of the proposed ENMPC and CHADPC schemes.
