• Abstract: Model Predictive Path Integral (MPPI) control is a sampling-based optimization method that has recently attracted attention, particularly in the robotics and reinforcement learning communities. MPPI has been widely applied as a GPU-accelerated random search method to deterministic direct single-shooting optimal control problems arising in model predictive control (MPC) formulations. MPPI offers several key advantages, including flexibility, robustness, ease of implementation, and inherent parallelizability. However, its performance can deteriorate in high-dimensional settings since the optimal control problem is solved via Monte Carlo sampling. To address this limitation, this paper proposes an enhanced MPPI method that incorporates a Jacobian reconstruction technique and the second-order Generalized Gauss-Newton method. This novel approach is called \textit{Gauss-Newton accelerated MPPI}. The numerical results show that the Gauss-Newton accelerated MPPI approach substantially improves MPPI scalability and computational efficiency while preserving the key benefits of the classical MPPI framework, making it a promising approach even for high-dimensional problems.

  We characterize the convergence property of a widely used sampling-based Model Predictive Path Integral Control (MPPI) method. We show that MPPI enjoys at least linear convergence rates when the optimization is quadratic, which covers time-varying LQR systems. Our theoretical analysis directly leads to a novel sampling-based MPC algorithm, CoVo-MPC. Empirically, CoVo-MPC significantly outperforms standard MPPI by 43-54% in both simulations and real-world quad agile control tasks.
