Header height control of combine harvester via robust feedback linearization
Studies have shown that feedback linearization can provide an effective controller for many types of nonlinear systems. It is known, however, that these controllers are not robust, in particular to model uncertainties as the feedback linearization process involves canceling of nonlinearities in the dynamics using an exact model which is seldom available. Although there are several strategies to...
متن کاملCoordinated Control of a Tractor-Trailer and a Combine Harvester by Neural Adaptive Robust Control
In this paper, the coordinated control problem of a tractor-trailer and a combine harvester is taken into account in the presence of model uncertainties by using the leader-following approach to track a reference trajectory for the first time. At first, a second-order leader-follower dynamic model is developed in Euler-Lagrange form which preserves all structural properties of the dynamic model...
متن کاملEvaluation of Combine Harvester Operation Costs in Different Working Conditions
Combine harvesters have a very important task in grain crop harvesting. Combine harvesters must fulfil lot of technological requirements regarding the field conditions, crop type, as well as the quality performance and optimal costs. The problem is that it is the main harvesting technology of cereals in the world and it has seasonal character of work, which has to be done in a relatively short ...
متن کاملA Pvdf Sensor for Monitoring Grain Loss in Combine Harvester
Grain loss sensor is an important monitoring module to realize the intelligent automatic control in combine harvester. Polyvinylidene fluoride piezoelectricity film has been one of the most widely used macromolecule materials at present. Based on its piezoelectric effect, in this paper, a grain loss monitoring system for combine harvester by using the PVDF sensor was designed. The system is com...
متن کاملSound Quantity and Quality of Sampo 3065 Combine Harvester
ABSTRACT- Noise is considered as one of the most debilitating conditions in farming operations. In this study, a number of factors affecting the noise generated by Sampo 3065 combine harvesters were evaluated. Factors were engine speed and gear ratio for combines with and without original cabins. A factorial experiment arranged as a completely randomized design with four replicates was used. Re...
