The model predictive path integral (MPPI) controller is a novel approach for autonomous vehicle control based on stochastic sampling of trajectories. The method is derivative free, and can handle complex non-linear dynamics and cost functions, which makes it ideal for performing aggressive maneuvers w...
Model Predictive Path Integral (MPPI) control framework algorithms have been studied for use in autonomous control systems because they are convenient to implement using model predictive trajectory samples with a stochastic control approach. They can also deal extensivlely with complex desired costs and...
In this paper, a model predictive path integral control algorithm based on a generalized importance sampling scheme is developed and parallel optimization via sampling is performed using a graphics processing unit. The proposed generalized importance sampling scheme allows for changes in the drift and di...
