✦ Synopsis

Longitudinal accelerations and yawing angular accelerations of a tractor induce horizontal flexible spray boom deformations which cannot be reduced sufficiently by simple structural adaptations. An electro-hydraulic control system has therefore been developed in order to attenuate the negative effect of longitudinal tractor accelerations on a spray boom. The linear quadratic Gaussian theory with loop transfer recovery has been used to design the compensator. Four different variants of the compensator are implemented in an experimental set-up to test the performance and the robustness of the feedback system and to investigate the applicability of the electro-hydraulic devices in active vibration control.

This approach aims to minimize all of the reflective waves at actuator positions located at the structural boundaries. A variation of the transfer matrix method shows the property that the elastic m

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

## Abstract A new suboptimal control design technique is proposed for a class of cascaded non‐linear systems. The design is based on a forward recursive design rather than a backstepping design, and it utilizes a non‐linear tracker derived using the state‐dependent algebraic Riccati equation approa
