A system and method for controlling a device such that device operates in a smooth manner. The system may switch between control architectures or vary gain coefficients used in a control loop to control the device. As the architecture or gains are switched, the control signal may be smoothed so that the device does not experience an abrupt change in the control signal it receives. In one embodiment, the control signal may be smoothed by adding a decaying offset value to the control signal to create a smoothed control signal that is applied to the device.

L'invention concerne un système et un procédé conçus pour commander un dispositif de façon que ce dernier fonctionne de manière régulière. Le système peut commuter entre des architectures de commande ou modifier des coefficients de gain utilisés dans une boucle de commande pour commander ledit dispositif. Simultanément à la commutation de l'architecture ou des gains, le signal de commande peut être lissé afin que le signal de commande que le dispositif reçoit ne subisse pas un changement brusque. Dans un mode de réalisation, on peut lisser le signal de commande en lui ajoutant une valeur de correction décroissante afin de créer un signal de commande lissé applicable au dispositif.
