Distributed nonlinear model predictive control of an autonomous tractor-trailer system

no code implementations20 Apr 2021 Erkan Kayacan, Erdal Kayacan, Herman Ramon, Wouter Saeys

This paper addresses the trajectory tracking problem of an autonomous tractor-trailer system by using a fast distributed nonlinear model predictive control algorithm in combination with nonlinear moving horizon estimation for the state and parameter estimation in which constraints on the inputs and the states can be incorporated.

Towards Agrobots: Trajectory Control of an Autonomous Tractor Using Type-2 Fuzzy Logic Controllers

no code implementations9 Apr 2021 Erdal Kayacan, Erkan Kayacan, Herman Ramon, Okyay Kaynak, Wouter Saeys

Autonomous navigation of an agricultural vehicle involves the control of different dynamic subsystems, such as the yaw angle dynamics and the longitudinal speed dynamics.

Learning in Centralized Nonlinear Model Predictive Control: Application to an Autonomous Tractor-Trailer System

no code implementations5 Apr 2021 Erkan Kayacan, Erdal Kayacan, Herman Ramon, Wouter Saeys

One of the most critical tasks in tractor operation is the accurate steering during field operations, e. g., accurate trajectory following during mechanical weeding or spraying, to avoid damaging the crop or planting when there is no crop yet.

Experimental Validation of Linear and Nonlinear MPC on an Articulated Unmanned Ground Vehicle

no code implementations25 Mar 2021 Erkan Kayacan, Wouter Saeys, Herman Ramon, Calin Belta, Joshua M. Peschel

The experimental results for a time-based trajectory show that the NMHE-NMPC framework with the proposed real-time iteration scheme gives better trajectory tracking performance than the ISL-LMPC framework and the required computation time is feasible for real-time applications.
