Abstract
A method is provided for controlling an actuator comprising an electromagnet and a control device, the electromagnet including a coil and a moving part that moves between a first position and a second position, the control device including a power supply member configured to supply the coil with an electric current having a voltage and an amperage and a measurement member for measuring a value of a quantity from among the voltage and the amperage. The method includes acquiring samples of the measured value, of regulating, according to a proportional-integral-derivative algorithm, the electric current to around a setpoint value that is equal to a maintenance value capable of maintaining the moving part in the second position, of comparing each sample to a predetermined threshold and of detecting a movement of the moving part if a single sample is above or equal to the threshold.
