<p>Method and system for controlling the actuator of a small-opening and regulated-delivery valve. System for controlling the actuator of a partial exhaust gas recirculation valve (16) in an internal combustion engine (10) for a motor vehicle equipped with at least one means (12) of measuring the flowrate of air admitted and with at least one circuit (15) for partial exhaust gas recirculation and controlled by a means (17) of controlling the admitted gases which is able to determine an admitted-air setpoint value, . the control system comprising a means of comparing the flowrate measurement against a flowrate setpoint value (19) able to emit a setpoint value for the position of the actuator which is regulated by an actuator control means (22) capable of preventing damage to the valve, . a means (23) of determining a break in regulation, a means (24) of determining resumed regulation, which means are connected to a regulation control means (25) able to stop regulation and close the valve at a velocity profile that protects the valve from damage when the position of the valve reaches a predefined threshold position indicating that it is near its end stops.</p> |
