Sensor Placement for Driveline Control

Abstract Vehicular drivelines can be instrumented with sensors in different locations. Control and damping of torsional oscillations will therefore lead to, depending on sensor location, control problems where the control objective signal is not the same as the measured output signal. It turns out that it is convenient to work with a modified complementary sensitivity function, being modified with a dynamic output ratio. The specific characteristics of a driveline model is analyzed using these concepts, and the consequences for design of feedback controllers are discussed.
