The present patent application relates to a method and system for providing active vibration isolation of a non-linear dynamic system in an automotive vehicle. An implicit, arbitrarily detailed multi-body simulation model of the system is built, Non-linear elements to be controlled are identified. The non-linear elements are modeled as a linear one in parallel with a non-linear parameter dependent element, which is considered as an 'input' and the parameter as an 'output' and a linear analytical model representing this input/output relation is computed. The model 'input' is substituted by a corresponding parameter dependent expression utilizing the 'output' whereby a linear parameter varying model (LPV-model) of the system suitable for control synthesis is yielded. The LPV-model of the system is used for the synthesis of a controller, which is used to control one or more actuators to generate a respective force output for canceling any vibration induced forces generated by the system.
