Multi-Sensor Wheel Slip Estimation and Compensated NMPC for Trajectory Tracking of Skid-Steered Mobile Robot
During trajectory tracking in complex outdoor environments, skid-steered mobile robots are prone to slip disturbances arising from wheel-ground contact. This paper proposes a real-time wheel slip estimator and integrates it into the nonlinear model predict control (NMPC) framework. First, a wheel slip dynamics model is...
