摘要:
我们提出了一种动态环境安全导航的新框架,将 Koopman 算子理论与 conformal prediction 相结合。该方法利用数据驱动的 Koopman 逼近学习非线性动力学,并采用 conformal prediction 量化不确定性,为逼近误差提供统计保证。该不确定性通过约束收紧有效融入 Model Predictive Controller (MPC) 公式中,确保稳健的安全保证。我们实现了分层控制架构,参考生成器为安全导航提供航点。我们在仿真中验证了方法的有效性。
英文摘要:
We propose a novel framework for safe navigation in dynamic environments by integrating Koopman operator theory with conformal prediction. Our approach leverages data-driven Koopman approximation to learn nonlinear dynamics and employs conformal prediction to quantify uncertainty, providing statistical guarantees on approximation errors. This uncertainty is effectively incorporated into a Model Predictive Controller (MPC) formulation through constraint tightening, ensuring robust safety guarantees. We implement a layered control architecture with a reference generator providing waypoints for safe navigation. The effectiveness of our methods is validated in simulation.
