Project description:

Today, it is a major challenge for power intensive industries to optimize their energy strategy in order to ensure long-term sustainable economic growth. Strategies for engineering systems to improve their energy efficiency are timely and vital. This project intends to unravel a practical question: can we improve the energy efficiency of engineering systems through judiciously switching between their coexisting states? This project seeks to explore a frontier research area in dynamics and control to improve the energy efficiency of multistable engineering systems via implementing a novel minimal energy control.

The proposed research aims to develop a novel control strategy for multistable engineering systems in order to maintain their performance within a satisfactory level by implementing an energy-optimal steering. This will be achieved by studying a novel non-smooth dynamical system, namely the vibro-impact capsule system through both theoretical development and experimental validation. In the long term, this project will be fundamental for the realization of energy efficient control, which will provide safe, reliable, and efficient operations for future engineering systems.

The approach to realize this PhD project is: (1) to study multistability in vibro-impact systems (e.g. impact oscillator) and its basins of attraction numerically and experimentally; (2) to develop a new control strategy for switching between different coexisting attractors; and (3) to verify the proposed control strategy experimentally using the experimental rig of the capsule system.
