Terramechanics-Inspired Sensor Fusion for Slip and Mass Flow Estimation in Agricultural Conveyor Systems
Ruben Hefele, Timo Oksanen
Precision farming requires accurate knowledge of implement states. In organic fertilizer spreaders, heterogeneous material and variable field conditions complicate flow-rate predic…
Multi-Reference Path Tracking Control for an Agricultural Tractor with Nonlinear Model Predictive Control
Marcel Moll, Timo Oksanen
Guiding a tractor along a predefined reference path is a key component of precision agriculture. This study develops a path tracking controller based on Nonlinear Model Predictive…
Concept of a Sensor Test Environment for Dusty Agricultural Conditions
Peter Buckel, Johannes Hermann, Jonas Wollmann +2
Dust in agriculture presents a significant challenge for autonomous agricultural machinery. Dust can impair the performance of sensors and algorithms. This work, therefore, present…
EcoTIM: Fuel-saving multi-brand tillage with ISO 11783 TIM
Ruben Hefele, Timo Oksanen
Tillage operations account for a large share of on-farm diesel consumption, yet the fuel efficiency of the combined tractor-implement system is not optimised in current practice. M…
Smart Prism with Tilt Compensation for CAN bus on Mobile Machinery Using Robotic Total Stations
Sumesh Sharma, Marcel Moll, Timo Oksanen
Accurate reference trajectories are required to validate autonomous agricultural robots and highly automated off-road vehicles under real-world field conditions. In practice, robot…
