CONTROL METHOD OF VIBRATION AND NOISE FROM A VARIABLE DISPLACEMENT ENGINE USING AN ADAPTIVE ALGORITHM, CAPABLE OF EFFICIENTLY CONTROLLING VIBRATION AND NOISE

摘要

PURPOSE: A control method of vibration and noise from a variable displacement engine using an adaptive algorithm is provided to enable vibration or noise signal to be generated as a desired signal based on a conventional algorithm by the correcting of a target part.;CONSTITUTION: A control method of vibration and noise from a variable displacement engine using an adaptive algorithm comprises following steps. A first sensor on a given driving unit obtains a reference signal, which corresponds to RPM of the engine of the driving unit(S100). A second sensor on the driving unit obtains a target signal, which corresponds to the vibration from the driving unit(S200). If the number of the driving cylinders of the driving unit changes, a controller applies an adaptive algorithm, which outputs the same operation control signal to the target signal based on the reference signal and the target signal(S300). An actuator operates based on the operation control signal of the controller(S400).;COPYRIGHT KIPO 2011
