Abstract:
1. A method for damping oscillations in a driveline coupled to a powertrain system comprising a plurality of individually-controllable torque generative devices mechanically coupled to a transmission, the transmission configured to operate in one of a plurality of fixed gear and continuously variable operating modes, wherein a control module performs the following steps comprising: forming a first matrix comprising a plurality of reference operating states for the powertrain system for a selected one of the transmission operating modes; forming a feedback matrix comprising a second matrix including a plurality of feedback operating states for the powertrain system multiplied by a gain factor matrix, wherein the gain factor matrix corresponds to the selected transmission operating mode; determining state errors comprising comparing the first matrix and the feedback matrix; and, individually controlling torque outputs from the torque generative devices in response to the operating state parameters contained in the first matrix, the feedback matrix and the selected transmission operating mode.
