Resonant magnetic actuation system modelling and control
Magnetic actuation systems can be used to move surgical equipment such as catheters, endoscopes or guidewires using the force / torque acting on permanent / soft magnets. In addition to using magnetic fields for steering such equipment, oscillating and rotational magnetic fields may also be used to locomote untethered objects (such as microswimmers) or affect/catalyse chemical reactions.
Keywords: - Magnetic actuation system
- Dynamic Systems
The tasks for this projects consist of the following:
- Analyze / model the dynamics of a coupled resonator system consisting of three LC series resonators.
- Develop a control algorithm and implement it on a DSP
- Verify functionality by measuring the tracking performance of the system
The following experience can be useful for the project:
- Programming knowledge in C for DSPs
- Modelling of dynamic systems / electronics using software such as Simulink, LTSpice etc.
- Basic knowledge in power electronics (synchronous buck converter, full bridge, PWM control etc.).

In this project, the phase and magnitude of oscillating currents should be controlled in the coils of a magnetic actuation system in order to generate oscillating and rotating magnetic fields. These fields can be used to trigger chemical reactions using composite materials or to actuate microswimmers.
