Active Magnetic Bearings (AMB) in rotating machines are very advantageous since they allow motion with low friction. This facilitates
- Removal of lubricant
- Reduction of wear and tear
- Increase rotational speed limit
Due to high nonlinear couplings of the magnetic interactions, conventional linear control methods often fall short in terms of accuracy and range of operation.
This master project aims to the design, implementation and evaluation of nonlinear control strategies for an AMB system. The task of the project comprises the following tasks:
Develop a first-principle mathematical model of an AMBS or improving/extending an existing one to include the most dominant perturbations and disturbances.
- Define a suitable sliding surface that describe the desired dynamical properties of the closed-loop system (e.g. desired damping and bandwidth).
- Design a first-order Sliding Mode Controller that satisfies the performance specifications and modify the design to alleviate the effect of actuator chattering.
- Implement and tune the obtained design on the real AMB system.
- Design and carry out experiments for different operation scenarios.
- Define performance metrics and evaluate the designed controller.
