Abstract
L'invention concerne la compensation thermique des systèmes du second ordre pour obtenir un signal de sortie pratiquement indépendant des variations de l'amortissement. Le circuit compensateur 1 de l'invention est associé à un système du secon ordre 3 sensible à une grandeur d'entrée 4. Le système 3 fournit un signal brut es qui est traité par le compensateur 1 pour éliminer l'influence des variations d amortissement du système du second ordre 3. Le signal de sortie compensé ec est représentatif de la grandeur d'entrée 4 et pratiquement indépendant des variations de la température du fluide d'amortissement. L'invention est applicable aux instruments à inertie, et notamment aux gyroscopes et aux gyromètres.
