Zone controlled method for controlling a wastegate in a turbocharged internal combustion engine |
摘要 |
A method for controlling the wastegate (16) in a turbocharged internal combustion engine (1); the method contemplates the steps of: determining, during a design phase, a control law (CL) which provides an objective opening of a controlling actuator (35) of the wastegate (16) according to the supercharging pressure (P); determining an objective supercharging pressure (P obj ); measuring an actual supercharging pressure (P); determining a first open loop contribution (WG OL ) of an objective position (WG obj ) of a controlling actuator (35) of the wastegate (16) by means of the control law (CL) and according to the objective supercharging pressure (P obj ); determining a second closed loop contribution (WG CL1 ) of the objective position (WG obj ) of the controlling actuator (35) of the wastegate (16); and calculating the objective position (WG obj ) of the controlling actuator (35) of the wastegate (16) by adding the two contributions (WG OL ,WG CL1 ).
