Semi-formal verification of closed-loop specifications in the concept design phase

Autor: Jan H. Richter, Stefan R. Friedrich

Publikováno v: at - Automatisierungstechnik. 65:115-123

The article addresses the semi-formal verification of behavioral specifications for subsystems consisting of physical parts and controllers, complemented by simulation-based integration testing. Since design errors in early phases tend to be particul

Robust Backlash Estimation for Industrial Drive-Train Systems—Theory and Validation

Autor: Dimitrios Papageorgiou, Jan H. Richter, Hans Henrik Niemann, Mogens Blanke

Publikováno v: Papageorgiou, D, Blanke, M, Niemann, H H & Richter, J H 2019, ' Robust Backlash Estimation for Industrial Drive-Train Systems—Theory and Validation ', IEEE Transactions on Control Systems Technology, vol. 27, no. 5, pp. 1847-1861 . https://doi.org/10.1109/TCST.2018.2837642

Backlash compensation is used in modern machine-tool controls to ensure high-accuracy positioning. When wear of a machine causes deadzone width to increase, high-accuracy control may be maintained if the deadzone is accurately estimated. Deadzone est
