Double corrector for asymmetric mechanism compensation

摘要

The invention relates to a method for controlling a mechanism (10) having an asymmetrical behavior, the mechanism (10) comprising a first operating direction (F +) and a second operating direction (F-), the control method allowing generate, using a control module (24) of a computer (20), a control signal (x_com) from a setpoint signal (x_cons), in which - when the signal setpoint (x_cons) indicates to operate the mechanism (10) in the first direction (F +), the control module (24) applies a first corrector (100) to the setpoint signal (x_cons) to generate a control signal (x_com ), - when the setpoint signal (x_cons) indicates to operate the mechanism (10) in the second direction (F-), the control module (24) applies a second corrector (100) to the setpoint signal (x_cons) to generate a control signal (x_com), and wherein the first and second correctors (100, 20 0) have different parameters (Kp1, Kp2, Ti1, Ti2), in order to compensate for the asymmetrical behavior of the mechanism (10).
