In this paper, a hybrid model of a spray boom with cable suspension is developed. It combines an analytical modelling procedure with identi"cation techniques to cope with the limited power in the excitation actuator. The analytical model was used to optimize the passive boom suspension, while the id

✦ Synopsis
The objective of the study was to develop a simple, cheap and reliable system to investigate boom movements on a standard test track and under "eld conditions. A series of tests was conducted in the laboratory to investigate the accuracy of measurement and the reliability of such a system based on potentiometric transducers in comparison with a very precise and sophisticated infrared-ultrasonic system. The correspondence between the data of the two systems justi"es the adoption of the transducer system for the inspection of boom movements under "eld conditions.

To prevent local under-or over-application of chemicals, a spray boom must be kept parallel to the soil. On a slanted "eld, the operator, driving a sprayer equipped with a passive boom suspension, has to turn the boom manually in a skewed position. This paper presents the development of a slow activ
