Project description

Knowledge of dynamic forces and torques is critical, both during the prototype development stages of mechatronic products, machines and processes and during their operational life. Measuring forces is a time-consuming, error-prone, expensive and often drastic process. It also regularly happens that force measurements at the desired locations are prohibited due to lack of space or too harsh conditions.

Main Objective: The main objective of the project is to develop a breakthrough force / torque measurement technology by applying a virtual detection strategy. This includes the evaluation and development of single (Kalman filter-based) and multi-step (Moving Horizon Estimation based) estimators that combine faithful physical models and physically inspired grey box models with affordable, non-intrusive sensors to rapidly (potentially real) unknown forces. -time), accurate, in-situ and online. The target performance is defined in collaboration with industry and includes real-time in-situ power estimation with a bandwidth of 10 Hz and a dynamic range of 20 dB to on-line in-situ power estimation with a bandwidth of 200 Hz and a dynamic range of 80 db. Range. The estimation technologies must be able to account for the non-linear dynamic effects as they occur in mechatronic powertrains and systems.
