On powertrain oscillation damping using feedforward and LQ feedback control

Torsional resonances in the vehicle powertrain are a problem in the automotive industry, since they affect the driveability in a negative way. This paper aims at modelling, control design and verification of a heavy duty powertrain. A model based control system with the aim of damping the powertrain oscillations has been developed, using feedforward and feedback control. The control system has been tested in simulations in Matlab/Simulink and experimental tests are underway
