METHOD AND SYSTEM FOR CONTROLLING AN ELECTROMAGNETIC VALVE ACTUATOR OF A THERMAL MOTOR

摘要

The invention relates primarily to a method of controlling an electromagnetic actuator (9) for a thermal engine valve without a compression spring, characterized in that said method comprises: a step of calculating a position command (Zref (k)) according to a parameterizable profile adapted to the operation of said engine from a crankshaft angle, - a step of calculating a pre-command (PRE) from, in particular, said position command (Zref (k) ) and a pressure measured at said valve, - a step of calculating a regulation term on the difference between said position setpoint (Zref (k)) and a measured position (Zmes (k)), - a step of calculating a command of said actuator (9) from the sum of said pre-command (PRE) and said regulation term, and - a step of controlling said actuator (9) from the calculated command.
