Réglage, analyse et validation

Réglage des paramètres du système de contrôle et analyse des résultats en ligne de commande

Une fois que votre modèle a été configuré pour le réglage, la commande systune ajuste les coefficients réglables afin de répondre à vos exigences de design. Pour valider les résultats, examinez les réponses du système et évaluez le niveau de satisfaction de vos objectifs de réglage. Dans le cas d’un système de contrôle modélisé dans Simulink^®, écrivez les valeurs des paramètres réglés dans le modèle afin qu’il soit validé par rapport au système non linéaire complet. Pour plus d’informations, consultez Validate Tuned Control System.

Rubriques

Fondamentaux du réglage

Tune Control System at the Command Line
After building a tunable control system model and specifying tuning goals, use systune to tune the parameters of your system.
Tuning Multiloop Control Systems
Jointly tune the inner and outer loops of a cascade architecture with systune.
Speed Up Tuning with Parallel Computing Toolbox Software
If you have the Parallel Computing Toolbox™ software installed, you can speed up the tuning of fixed-structure control systems.

Analyse et validation

Interpret Numeric Tuning Results
Tuning reports from systune and Control System Tuner give you an overview of how well the tuned control system meets your tuning goals.
Visualize Tuning Goals
Tuning-goal plots let you visualize your design requirements against tuned system responses, to see where and by how much tuning goals are satisfied or violated.
Validate Tuned Control System
When you tune a control system, validate the results by examining system responses with the tuned parameters.
Extract Responses from Tuned MATLAB Model at the Command Line
Analyze responses of a tuned control system by using getIOTransfer and related functions to compute responses between various points in the model.
Validating Results
This example shows how to interpret and validate tuning results from systune.
