Robust output-feedback control for container-slosh system using Variable Gain Super-twisting Algorithm

This paper presents robust control of container-slosh coupled dynamical system. Variable Gain Super-twisting Algorithm (VGSTA) is used to synthesize an output-feedback control. The surface used is finite time converging. The detailed stability proof is presented. The proposed controller is compared with classical PID. The proposed method is verified via rigorous simulations. The robustness analysis is also validated in simulations.
