The liquid in a liquid storage container, e. g. an oil, tank, starts to vibrate in earthquakes and other cases. This paper describes an active adaptive control method to suppress this liquid sloshing vibration avoiding the liquid container from being damaged. This study considers a nonlinear friction between the liquid container and the ground. We propose the usage of an adaptive observer, which is based on a basic model of the container. This model is considered the first order vibration mode of the liquid in a vertical plane. The efficiency of this control method for suppressing the liquid sloshing vibration has been shown by simulations and experiments.
