Shape Memory Alloy actuators are microactuators that are known for their high actuation-force and -strain. Limiting the application of Shape Memory Alloy actuators is the lack of suitable control algorithms that can deal with the highly non-linear dynamics of the actuator. The latter suffers from hysteresis and is characterized by the changing(More)
Control schemes employing inverse-based hysteresis compensation are successful in accurate position control of smart material actuators. However, the effectiveness of the inverse hysteresis model in cancelling hysteresis is not addressed in the evaluation of these control schemes. Classical methods rely on closed-loop tracking error analysis which does not(More)
Geometric calibrations of medical imaging systems are crucial to allow for advanced (X-ray) imaging techniques. Developments in medical procedures, lightweight system design and the growing costs of healthcare, leads to the desire for simpler and faster calibration approaches. The aim of this paper is to present a novel approach to enhance system(More)
