Abstract (en)

Method for controlling a throttle valve of an internal combustion engine, the valve comprising an electric actuator for controlling a position of a shutter and a position sensor for detecting the position of the shutter, the method comprising a step of controlling said actuator by means of a cascade control scheme comprising an inner control loop and an outer control loop, so as to generate a control signal (Volt_act) given by the difference between a proportional contribution and an integral contribution, wherein the proportional contribution (Pω * e_vel) is a function of the signal generated by a controller (C1) of the outer loop and wherein the integral contribution (C_stim) is a function of at least a position estimation error (e_stim) between an estimated position (pos_stim) by means of an estimator and a measured position (pos_mis) by means of the position sensor.
