Préparation du modèle
Le passage de la simulation desktop à la simulation temps réel est un processus itératif qui peut nécessiter une reconfiguration approfondie du modèle. Le workflow de préparation du modèle temps réel montre comment analyser et réduire le coût de calcul de votre modèle sur une machine de développement. Après avoir suivi ce workflow, vous pouvez déterminer les paramètres optimaux du solveur à coût fixe pour la simulation sur une machine cible temps réel.
Rubriques
- Model Preparation Process
Follow the real-time model preparation workflow to make your Simscape™ model real-time capable.
- Solvers for Real-Time Simulation
The fixed-step solver, step size, and number of iterations that you specify affect how your Simscape model simulates in real time.
- Improving Speed and Accuracy
Simulating a Simscape model in real time requires a balance of speed and accuracy that you can attain by reducing computational costs, optimizing solver configurations, or increasing processing power.
- Reduce Fast Dynamics
To make your Simscape model real-time capable, decrease computational cost by reducing fast dynamics that you identify using frequency-response and pole-speed analyses.
Sélection d՚exemples
Determine Step Size
Determine the maximum step size to use for fixed-step simulation by analyzing the results from a variable-step simulation of your Simscape model.
Increase Simulation Speed Using the Partitioning Solver
