DOUBLE CORRECTOR FOR ASYMMETRICAL MECHANISM COMPENSATION

The invention concerns a method for controlling a mechanism (10) displaying asymmetrical behaviour, the mechanism (10) comprising a first operating direction (F+) and a second operating direction (F−), the control method making it possible to 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 setpoint signal (x_cons) indicates that the mechanism (10) should be operated in the first direction (F+), the control module (24) applies a first corrector (100) to the setpoint signal (x_cons) in order to generate a control signal (x_com),—when the setpoint signal (x_cons) indicates that the mechanism (10) should be operated in the second direction (F−), the control module (24) applies a second corrector (100) to the setpoint signal (x_cons) in order to generate a control signal (x_com), and in which the first and second correctors (100, 200) have different parameters (Kp1, Kp2, Ti1, Ti2), in order to compensate for the asymmetrical behaviour of the mechanism (10).

A controller is configured to control a system by generating a control input to an actuator changing a state of the system in accordance with the control input. The controller includes an interface configured to receive data indicative of dynamic response of the actuator and a tuner configured to determine the maximum rate of change of the control input during a control cycle using the received data indicative of dynamic response of the actuator. The controller also includes a receiver configured to receive measurements of the state of the system and a solver configured to determine a current value of the control input for controlling the controlled system based on the state of the controlled system subject to constraints on operation of the system and a constraint on the maximum rate of change of the control input, and to cause the actuator to change the state of the system according to the current value of the control input.

Double corrector for asymmetrical mechanism compensation

The invention concerns a method for controlling a mechanism (10) displaying asymmetrical behaviour, the mechanism (10) comprising a first operating direction (F+) and a second operating direction (F?), the control method making it possible to generate, using a control module (24) of a computer (20), a control signal (x_com) from a setpoint signal (x_cons), in whichwhen the setpoint signal (x_cons) indicates that the mechanism (10) should be operated in the first direction (F+), the control module (24) applies a first corrector (100) to the setpoint signal (x_cons) in order to generate a control signal (x_com),when the setpoint signal (x_cons) indicates that the mechanism (10) should be operated in the second direction (F?), the control module (24) applies a second corrector (100) to the setpoint signal (x_cons) in order to generate a control signal (x_com), and in which the first and second correctors (100, 200) have different parameters (Kp1, Kp2, Ti1, Ti2), in order to compensate for the asymmetrical behaviour of the mechanism (10).
