Device and method for active control of a force feedback for a control device

摘要

The invention concerns a device for the active control of a force feedback for a control device, comprising a calculator, a position sensor (3) configured to provide the calculator with an effective position signal (Pm) of the control device, and an actuator (2) ensuring the displacement of the control device at the command of the calculator, the calculator being configured to use the effective position signal and modulate a setpoint current (lc) delivered to the actuator to ensure the position feedback of the displacement of the control device, characterized in that the calculator is further configured to create at least one saturation terminal (Bsat+, Bsat−) according to a predetermined function of the value of the effective position signal of the position/force law kind, and to saturate the setpoint current using the at least one saturation terminal.

1. A device for active control of a force feedback for a steering member, comprising a calculator, a position sensor (3) configured to provide the calculator with an effective position signal (Pm) of the steering member, and an actuator (2) ensuring displacement of the steering member on command from the calculator, the calculator being configured to execute the effective position signal and modulate a setpoint current (Ic) delivered to the actuator to ensure position-controlled displacement of the steering member,
characterized in that the calculator is also configured to develop at least one saturation terminal (Bsat, Bsat+, Bsat−, Bsat-cor) according to a predetermined function of a value of the effective position signal of position/force law type (21, 23, 32), and to saturate the setpoint current by means of the at least one saturation terminal, wherein the calculator further comprises a speed estimator (10) executing the effective position signal (Pro) to provide an effective speed signal (Vm), and wherein the calculator further develops the at least one saturation terminal according to a second predetermined function of the value of the effective speed signal of speed/force law type (21˜31).
