1. Estimation of torque in heavy duty vehicles with focus on sensor hysteresis
Sammanfattning : For diagnosis and feedback control of vehicle powertrains, it is highly desired to monitor the torques at different locations online. The most obvious way to do this is to measure cylinder pressures, from which cylinder individual delivered torques can be calculated, or to use torque sensors. LÄS MER
2. Implementation, identification, and adaptation of Preisach like hysteresis models
Sammanfattning : The extended generalized Prandtl-Ishlinskii model (XGPI) of hysteresis has a wide applicability, partly because of its capability of modelling highly asymmetric hystereses. For a given parameterization, it is typically identified using non-linear least squares optimization with concomitant problems of convergence, dependence on initial parameter guess and local minima.
