Dynamic modeling and trajectory tracking control of unmanned tracked vehicles

Robotics and Autonomous Systems, 2018
Abstract Tracked vehicles have inherent advantages over wheeled vehicles, as the former provide stable locomotion on loose and uneven terrain. However, compared with the latter, the slippage generated due to the complex, nonlinear track-terrain interactions during skid-steering to follow a curve, brings about difficulties preventing the accurate ...

Safe Trajectory Tracking in Uncertain Environments

, 2022
In Model Predictive Control\ua0(MPC) formulations of trajectory tracking problems, infeasible reference trajectories and a-priori unknown constraints can lead to cumbersome designs, aggressive tracking, and loss of recursive feasibility. This is the case,
