The control system of the ESO 100 m telescope (OWL) has to reject slow and fast perturbations in several subsystems. In this paper we focus on the wind rejection control strategies for two subsystems: the main axes and the segmented mirror. It is shown tha ...
This paper focuses on applications in the area of WAMS (wide area measurement systems) and WACS (wide area control systems) development. A main issue is the report of an international cooperation oriented to test new algorithms and methods in this field. A ...
When running a fuel cell system in load following mode, several operating points (i.e. a combination of gas flow rates, pressures, humidities, temperatures and current density) can provide the required net power. Typically, only one of those operating poin ...
The Autonomous Systems Lab of EPFL3 is developing, within the framework of an ESA program, an ultra-lightweight solar autonomous model airplane called Sky-Sailor with embedded navigation and control systems. The main goal of this project is to jointly unde ...
We are developing a swarm-intelligent inspection system based on a swarm of autonomous, miniature robots, using only on-board, local sensors. To estimate intrinsic advantages and limitations of the proposed possible distributed control solution, we capture ...
Maintaining a fuel cell system in correct operating conditions when subjected to fast load changes requires good system control. Best results are typically achieved using model based control strategies. This paper elaborates a control oriented PEM fuel cel ...
A novel mechanical structure design with reduced deflection offset is reported. This design offers a batch processing solution to a well-known problem in the fabrication of very thin crystalline silicon structures, that is initial bending due to anchoring ...
AHeart is a sofware that helps control algorithm designers implement their ideas independently of the underlying commercial building automation and control system. ...
Introducing automatic control has always been challenging. As a technology, control is generally hidden by the enclosing application. As a methodology, control is often seen as a theoretical subject. Therefore, to grasp the interest of both practitioners e ...
Many applications in materials science, life science and process control would benefit from atomic force microscopes (AFM) with higher scan speeds. To achieve this, the performance of many of the AFM components has to be increased. In this work, we focus o ...
