The limiter comprises a magnetic circuit (2) including a core (20) and at least one inductive coil (S) wound around the core (20) and connected to (i) the AC current source (S) and (ii) the load (C), said coil (1) having an impedance. The limiter is characterized in that it also comprises a virtual air-gap (EV) that includes: at least one pair (40) of holes (4) in the magnetic circuit (2); and a winding (3) which is wound between the holes (4) of each pair (40) of holes (4) and connected to a DC current source (5), said limiter (10) operating between at least two states.

Abstract

The invention relates to a method of regulating traffic on a main traffic route (2) through the control of an actuator (3) controlling access of vehicles to the main route (2) from an access route (7), in which: - at least one sensor (6) measures the density of vehicles on the main route (2), - a control device (4), linked to the sensor (6) and implementing a model‑free estimation of the behaviour of the flow of the vehicles on the main route (2), calculates a first control variable - the control device (4) determines a control variable by taking account of the first control variable; - the control device (4) despatches the control variable to the actuator (3); - the actuator (3) controls access by permitting or denying the access of the vehicles on the main route (2) as a function of the control variable, so that the traffic on the main route (2) is regulated.
