“…Due to the different types of these two systems of equations, dealing with them creates different challenges in the PDE-control context. The two recent works that focus on the PDE controller/observer design based on the NSEs are in Jokar et al (2023Jokar et al ( , 2022. In these two works, we have constructed a state-feedback law (i.e., Jokar et al, 2022) and an output-feedback law (i.e., Jokar et al, 2023) that guarantee a slosh-free asymptotic convergence of liquid-filled satellites/rigid bodies to the desired attitude.…”

“…From a PDE control theoretical viewpoint, we encounter with two types of liquid systems of equations: (i) the full form of NSEs, which are parabolic-type PDEs (see Jokar et al, 2023, 2022) and (ii) the Saint-Venant equations (SVEs) which are hyperbolic type PDEs (see e.g., Diagne et al, 2017b; Karafyllis et al, 2023, 2022). Due to the different types of these two systems of equations, dealing with them creates different challenges in the PDE-control context.…”

“…Compared to current achievements, the main innovations of the present paper are as the following:1. In contrast to Jokar et al (2023, 2022) that consider NSEs (that are parabolic PDEs) to depict the liquid motion, the present paper’s objective is to use the SVEs for modeling the liquid dynamics. We like to emphasize that the SVEs are basically hyperbolic PDEs cascaded with the ODE of the rigid body, leading to a global hyperbolic PDE-ODE cascade structure.…”

Moreover, unlike Jokar et al (2023, 2022) which consider the attitude dynamics of rigid bodies, here, we focus on the translational motion.2. Compared to Karafyllis et al (2022, 2023) and Karafyllis and Krstic (2022), we regard the rigid body dynamics, which leads to the addition of an ODE in cascade with the SVEs.…”

We solve the boundary output-feedback tracking problem for a moving rigid body-liquid system described by the linearized Saint-Venant PDEs. The control input is an external force acting on the rigid body. The control law is a boundary state-feedback type augmented with a Luenberger boundary observer, leading to a dynamic feedback law. The main complexity lies in the fact that we can only measure the position and velocity of the rigid body. To get around this limitation, the observer estimates the liquid levels at the cavity walls. We utilize a control Lyapunov functional methodology (with two different functionals for the observer and the dynamic feedback law) and achieve a slosh-free asymptotic convergence to the prespecified equilibrium point (in the sense of an appropriate norm). Finally, through a simulation, we demonstrate the feasibility of the boundary output-feedback controller for the (linear and nonlinear) system.
