Abstract:
1. Method for controlling the wastegate ( 16 ) in an internal combustion engine ( 1 ) turbocharged by means of a turbocharger ( 12 ); the control method comprises the steps of: determining, during a design phase, a control law (CL) which provides an objective opening of a controlling actuator ( determining an objective supercharging pressure (P measuring an actual supercharging pressure (P); determining a first open loop contribution (WG determining a second closed loop contribution (WG calculating the objective position (WG controlling the controlling actuator ( the step of determining the second closed loop contribution (WG determining a virtual position (WGF) of the controlling actuator ( calculating a position error (ε determining the second closed loop contribution (WG
