ELECTRONIC CAMSHAFT MOTOR CONTROL FOR PISTON PUMP |
摘要 |
<p>A two (or more) piston pump system (10) is provided with both pumps (12) being crank (14) driven. The system does not have a mechanical camshaft, but a software algorithm, which acts like one in controller (20). The algorithm will LEARN and create a unique speed profile, which will mimic the mechanical camshaft. For practical purposes the speed profile of output gear is called Cam profile with software acting as an imaginary camshaft. The algorithm utilizes Crank Angle Estimation, Learn Curve Generation, Smoothing and Advance Timing Calculation.</p> |
