Lunch Lecture December hosted by MI- Partners (Cancelled)
Due to private circumstances the lunch lecture will be cancelled today. More information about when we organize this lecture again will follow soon.
The title is: Frame deformations control based on reduced order thermo-elastic models
Speaker: Walter Aarden, Mechatronic System Architect, MI-Partners
Thermal induced deformations in high precision systems can be one of the dominant contributions to the overall positioning accuracy. To reduce these errors, real-time error compensation methods or even active control can potentially be used. In this talk both the use of a compensation and correction method will be presented. In this talk a method is shown using temperature sensors, in combination with a reduced order thermo-elastic model, to estimate displacements and tilts of an optical unit and use this information to correct or compensate in-plane displacement errors at a point of interest. The compensation is done by adjusting the setpoint position of the high precision stage. The thermal correction is based on temperature control of water cooled plates in combination with local fluid stream heaters at several frame positions.
