Method for controlling with adaptivity a wastegate in a turbocharged internal combustion engine |
摘要 |
A method for controlling the wastegate in a turbocharged internal combustion engine including the steps of: determining, during a design phase, a control law which provides an objective opening of a controlling actuator of the wastegate according to the supercharging pressure; determining an objective supercharging pressure; measuring an actual supercharging pressure; determining a first open loop contribution of an objective position of a controlling actuator of the wastegate by means of the control law and according to the objective supercharging pressure; determining a second closed loop contribution of the objective position of the controlling actuator of the wastegate; and calculating the objective position of the controlling actuator of the wastegate by adding the two contributions.
