When learning skills from demonstrations, one is often required to think in advance about the appropriate task representation (usually in either operational or configuration spaces). We here propose a probabilistic approach for simultaneously learning and ...
Material costs and novel applications have directed research interests towards miniaturized, faster rotatory electric drives. The challenges of miniaturization have made magnetic bearings more attractive, which are naturally suited for high speeds and virt ...
In modern automated assembly lines, part feeders play an important role to separate and sort parts. Agility and flexibility are required to achieve a good yield for different types of parts. The common working principle is to vibrate a working plate driven ...
For truck and electric two-wheel applications, the design target is an electric motor with working point in the range of 18-20Nm @ 4000rpm functioning at ambient temperatures from -40°C to 105°C. The design will be based on an existing Sonceboz BLDC motor. ...
Many applications are limited by the performance of the motors that power them. In the small power range, slotless BLDC motors are commonly used due to their intrinsic high power density and smooth torque characteristic. However, recent work has shown that ...
A novel decomposition scheme to solve parametric non-convex programs as they arise in Nonlinear Model Predictive Control (NMPC) is presented. It consists of a fixed number of alternating proximal gradient steps and a dual update per time step. Hence, the p ...
Stepper motors are a very convenient and economical solution for accurate positioning applications where long lifetime and low wear are required. Their particularly simple open-loop operation reduces the number of control components to a minimum. However, ...
The force (F) and the power consumption (P ) of a magnetic actuator are modeled, measured and optimized in the context of developing micro-actuators for large arrays, such as in portable tactile displays for the visually impaired. We present a novel analyt ...
Debiotech SA, une entreprise spécialisée dans la conception d'instruments médicaux, développe actuellement une micropompe de type patch destinée au traitement du diabète. Cette pompe est construite à partir d'un composant MEMS qui possède un actionneur pie ...
This paper presents a convenient and cost-effective experimental tool for measuring the mobility characteristics of a mechanical structure. The objective is to demonstrate that the point mobility measurement can be performed using only an electrodynamic in ...
