Energy saving becomes more and more important. Therefore different improvements have been made in motor design, electronic devices and software in order to increase the overall efficiency of electronic motor drives. Permanent Magnet Synchronous Motors (PMS ...
In this paper an Iterative Learning Control (ILC) algorithm is proposed for a certain class of Linear Parameter Varying (LPV) systems whose dynamics change between iterations. Consistency of the algorithm in the presence of stochastic disturbances is shown ...

This paper presents a convenient way to invert the classical Preisach model to compensate the hysteresis of a piezoelectric stack actuator in real-time. The advantage of the proposed method lies in the possibility to track a stochastic signal and compensat ...
Programmable matter is a material that produces
distinctive shapes or patterns according to a given command.
Often they are composed of interconnected modular elements
that are able to make or break the connections or alter
relative orientation. We pre ...
Electronic door lock cylinders need some sort of mechanical actuator to toggle the locking state between open and closed. The main requirements are high security standards, low power consumption, reasonable production costs, and facile integration of the a ...
This paper presents a method to analytically model the self and mutual phase inductances of a brushless dc motor with a Faulhaber winding. The method of images is used to “remove” the motor iron parts in the model in order to analyze the winding completely ...

Industrial robotic systems often require high performance control of a number of converter-fed motors. Although the advantages of using industrial robots during the manufacturing process are numerous the initial capital cost of the robotic system can be pr ...
In this paper, we describe how motile microorganisms can be integrated with engineered microstructures to develop a micro-bio-robotic system. SU-8 microstructures blotted with swarmer cells of Serratia Marcescens in a monolayer are propelled by the bacteri ...
Conventional robot motion teaching methods use a teaching pendant or a motion capture device and are not the most convenient or intuitive ways to teach a robot sophisticated and fluid movements such as martial arts motions. Ideally, a robot could be set up ...
This paper introduces a promising technique, called the first-pulse technique, for detecting the rotor position of a brushless DC motor at standstill. The technique is based on the B-H hysteresis characteristics of the stator iron. Depending on the rotor p ...
