Deviation Detection in Dual Motor-Driven Industrial Doors
This thesis investigates sensorless methods for detecting collisions and added weight in dual motor-driven industrial doors, to enhance safety without additional hardware. The study is grounded in the safety requirements outlined in EN 12453:2017 and conducted in collaboration with ASSA ABLOY. By monitoring deviations in the torque-producing current (IQ) from the motors, the developed methods iden
