Dans les systèmes de positionnement de haute précision, les cycles limites induits par les effets de frottement entraînent une réduction significative des performances de positionnement ; en particulier lorsque le système d'asservissement utilise un contrôleur à gain élevé. En conséquence, la présente étude présente un schéma de compensation composé d'une fonction de zone morte et d'un terme intégral pour limiter le gain équivalent de contrôleurs non spécifiés à la plage stable. Le système de compensation proposé garantit non seulement que le système de boucle de rétroaction reste stable, mais fournit également un mécanisme simple et efficace pour empêcher les utilisateurs de définir par inadvertance des gains de commande qui dégradent les performances de positionnement du système. Les résultats de la simulation confirment la capacité du système de compensation de limite de gain à supprimer les effets des cycles limites et démontrent donc sa faisabilité pour des applications pratiques.

Abstract: In high-precision positioning systems, the limit cycles induced by friction effects result in a significant reduction in the positioning performance; particularly when the servo system utilizes a high gain controller. Accordingly, the current study presents a compensation scheme consisting of a dead-zone function and an integral term to limit the equivalent gain of unspecified controllers to the stable range. The proposed compensation scheme not only ensures that the feedback loop system remains stable, but also provides a simple and effective mechanism for preventing the users from inadvertently setting control gains which degrade the positioning performance of the system. The simulation results confirm the ability of the gain limit compensation scheme to suppress the effects of limit cycles and therefore demonstrate its feasibility for practical applications.
