ISHS Acta Horticulturae 406: II IFAC/ISHS Workshop :Mathematical & Control Applications in Agriculture & Horticulture

THE EFFECT OF ELECTRO-HYDRAULIC DEVICES ON THE PERFORMANCE AND STABILITY OF A FEEDBACK SYSTEM

Authors:   H. Ramon, J. De Baerdemaeker
Abstract:
Two different electro-hydraulic compensators which must attenuate horizontal flexible deformations of a slender beam are designed.

The performance of the second controller which incorporates only the dynamics of the beam, servovalve and cylinder, is strongly inferior to that of the first controller which takes into account the dynamics of the beam and the complete hydraulic system (hydraulic lines, valves, accumulators and hydraulic cylinder).
