CAMSHAFT PHASOR SYNCHRONIZATION SYSTEM FOR AN ENGINE

摘要

A camshaft phasor control system for an engine includes a first camshaft position sensor that generates a first camshaft position signal based on a position of a first camshaft. A first summer generates a first error signal based on the first camshaft position signal and a first commanded position signal. A control module generates a raw duty cycle based on the first error signal. A second summer generates a modified duty cycle based on the raw duty cycle and a modifier. The control module generates the modifier based on the first error signal and speed of the first camshaft relative to a second camshaft.
