主题
- 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.
