SUMMARY:

Agricultural productivity directly depends on the efficient application of fertilizers and plant protection products, which is usually carried out by ground spraying with a spray boom attached to the tractor. The need for the agricultural spray boom to be parallel to the ground during operation requires active suspension systems with controllers that reduce as much as possible the oscillations associated with the rolling movement. This work proposes the integration of the open-loop technique of zero-vibration (ZV) input shaping with robust model-based adaptive controllers, the MRAC and the VS-MRAC, comparing the results of two-degree-of-freedom (2-DoF) configurations. The robustness of VS-MRAC + ZV is evidenced with promising results in tracking and control signal when it is integrated into input shaping.
