As tramways in cities must adapt to the street layout, tight curves cause wear and noise. An active steered wheelset can reduce both wear and noise. For an active steered wheelset, a controller using µ-synthesis is derived and tested. To measure the needed controller inputs directly on the wheelset, a new hall sensor concept is developed and verified. The sensor additionally calculates an index which represents the current measurement quality. This helps to identify erroneous measurements due to disturbances and allows a safe wheelset operation.
The active steered wheelset is validated in test scenarios with a prototype of the hall sensor using a co-simulation with multi-body physics. Comparing the simulation results, a low lateral displacement showing a good running stability and curving performance is observed.
