Description

This research focus aims at developing advanced control strategies to suppress sloshing dynamics in liquid-filled containers during high-speed transfer. By leveraging novel feedforward control methods, the objective is to ensure efficient and rapid liquid transport while eliminating the negative impact of liquid sloshing. The research integrates dynamic models with geometric constraints, targeting both simple and arbitrarily shaped containers. Through robust simulation, experimental validation, and industry-focused solutions, the research provides tools to significantly improve handling and transport processes in various industrial applications.

Research Goals

  • Develop robust control strategies to suppress liquid sloshing in industrial environments.
  • Model and validate the control system for various container shapes using both simulation and experimental methods.
  • Improve trajectory planning to eliminate dominant sloshing modes during rapid container transfer.
  • Provide robust solutions for real-time applications, with adaptability to different liquid levels and container types.
