Abstract
A camshaft phasor control system for an engine includes a position control module. The position control module generates a position control signal based on a camshaft position command signal and a gain signal. A gain circuit generates the gain signal based on the position control signal and feeds the gain signal back to the position control module. The position control module positions a camshaft of the engine based on the gain signal.
Claims20
A camshaft phasor control system for an engine, comprising:
- a position control module that generates a position control signal based on a camshaft position command signal and a first gain signal;
- and
- a gain calculation circuit that generates said first gain signal based on said position control signal and that feeds said first gain signal back to said position control module,
- wherein said position control module positions a camshaft of the engine based on said first gain signal.
A control system for an engine, comprising:
- a camshaft sensor that generates a camshaft signal that is indicative of position of a camshaft of the engine;
- a main control module that generates a camshaft position command signal;
- a position control module that generates a position control signal based on said camshaft signal, said camshaft position command signal, and a first gain signal;
- and
- a gain circuit that receives said position control signal and generates a first gain signal based on said position control signal,
- wherein said position control module generates said position control signal to position the camshaft.
A method of operating a camshaft phasor control system for an engine, comprising:
- generating a position control signal based on a camshaft position command signal and a gain signal;
- generating said gain signal based on feedback of said position control signal;
- and
- positioning a camshaft of the engine based on said gain signal.
