Control-Oriented Identification of an Electromechanically Actuated Metal V-belt CVT 2004-40-0013

For analysis, control design and testing of an electromechanically actuated metal V-belt type CVT, a simulation model is built. Due to its complexity and nonlinear behavior, this model is not suitable for control design. To use control design techniques like H1 or μ-synthesis, linear transfer functions from all inputs to all outputs must be known. Using approximate realization techniques, step responses simulated with the model are analyzed. In this way, a linearized state-space representation of the system is obtained. The transfer functions show resonances around 8−10 [Hz], depending on the CVT ratio. Using MIMO-control, closed loop bandwidths that could be obtained are up to 10 [Hz] for ratio control and 15 [Hz] for slip control.
