Abstract: The control device of a movement simulator, between its input formed of a control signal and its output formed of a measured magnitude among its speed, its position and its acceleration, by a transfer function B(z?1)/A(z?1) includes a corrector synthesized from the modelling of the movement simulator and equivalent to a RST controller. The controller includes a reference input, a retro-action input whereon is applied the measured magnitude and an output producing the control signal. The transfer function between the reference input of the controller and the measured magnitude is H(z?1)/W(z?1). The device has a reference filter whose input is a sinusoidal reference signal c(t) at a frequency wc and applying at output a filtered reference signal on the reference input of the controller. The reference filter has a transfer function Rr(z?1)/Fr(z?1), whose denominator and numerator are adapted to ensure, for the frequency wc, effective tracking by the movement simulator of the sinusoidal reference.

Abstract: A tuning method for a motion simulator embarking a payload. The simulator includes a mechanical device, a mobile plate of which is capable of carrying a payload, and a control unit including a controller capable of position feedback controlling said plate. The method enables an automatic tuning of the controller in order to feedback control the system embarking a given payload.

Abstract: A tuning method for a motion simulator embarking a payload. the simulator includes a mechanical device, a mobile plate of which is capable of carrying a payload, and a control unit including a controller capable of position feedback controlling the plate. The method includes: an initial step for the synthesis of a robust controller enabling to control the mechanical device over a range of values of an inertia parameter extending between a minimum inertia parameter and a maximum inertia parameter and, after having positioned the given payload on the plate, a test step during which the mechanical device, controlled by the robust controller, is actuated according to a reference input; an identification step which, on the basis of the data of the test step, enables to determine the value of the inertia parameter; and, a final step of synthesis of an optimal controller adapted to the given payload.
