The Residual Koopman Model Predictive Control (RKMPC) framework integrates a baseline kinematic model with a data-driven residual Koopman model for vehicle control. This approach reduces training data requirements by approximately 80% compared to traditional KMPC while improving lateral error by up to 22.08% and maintaining real-time computational efficiency.
Key insights
- Integrating a mechanistic baseline model with a data-driven residual component significantly reduces the volume of training data required for effective nonlinear control compared to purely data-driven methods.
- Focusing the data-driven learning on the 'residual' dynamics allows for more efficient model training and improved generalization from limited, localized data.
- The hybrid approach preserves the interpretability and inherent stability of physical models while enhancing performance by robustly compensating for unmodeled dynamics and linearization errors.
