1. An architecture for controlling and/or supervising at least one actuator of a movable cowl of a thrust reverser of a nacelle, the at least one actuator being powered by at least one motor, the at least one actuator comprising at least one motor sensor, the architecture comprising:
an electronic control unit configured to determine a position of the movable cowl to provide a servo-control of the at least one actuator depending on setpoints; and
an electronic monitoring module electrically connected to the electronic control unit and independent of the electronic control unit for processing information generated by the at least one motor sensor and calculating, from the information, the position of the movable cowl of the thrust reverser for monitoring the position of the movable cowl at any time,
wherein the electronic control unit is configured to determine the position of the movable cowl based on data from the electronic monitoring module,
wherein the at least one motor sensor is an angular sensor configured to generate the information from an angle measurement of a rotor of the at least one motor, and
wherein, in a thrust reversal configuration, the architecture is configured to calculate the position of the movable cowl of the thrust reverser depending on an integral of an angle measurement of the rotor between an initial time, corresponding to an initial position of the movable cowl, and a given time t.
