✦ Synopsis

This paper investigates the use of state feedback techniques in the active control of twin link spray boom suspensions. A transfer function for a suspension and a state space formulation of the system dynamics are derived. It is shown how the states can be estimated from boom angle measurements coupled with the state space model of the system. Two types of design techniques are investigated, optimal control and pole placement, and their effect on controlling recovery from a pulse disturbance of vehicle angle investigated by simulation.

Both types of state feedback controller allow advantage to be taken of increased control effort in improving disturbance rejection but at the expense of using feedback gains higher than those of the existing proportional controller. This latter feature will render a state feedback controller more prone to sensor noise transmission and greater care will need to be taken with noise filtering if this is implemented.

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

Minimization of the norm of parametric feedback controllers which assign desired eigenvalues to the closed-loop system is achieved by implementation of vector companion forms described in an earlier paper. The simple algorithm which emerges gives insight into the mechanism by which parametric eigenv

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
