Control and damping of torsional oscillations in vehicular drivelines is an important problem. Different sensors locations give different transfer functions, Gm or Gl. These functions have the same poles, but have different relative degree and different zeros. The dynamic output ratio, Gl/Gm, exactly captures these differences and nothing else. The problem that the control objective is not the same as the measured output signal is handled by introducing a modified complementary sensitivity function, being modified with Gl/Gm. Both structural and parameter dependent aspects of sensor placement will be characterized. In LQG/LTR (Linear Quadratic Gaussian/Loop Transfer Recovery), parameter dependent properties dominate in the LQG-step of the design, whereas structural properties dominate in the LTR-step.
