Characteristics of Automatic Contour-following Machine using Pneumatic-Hydraulic Control Element (Part 2)

Characteristics of Control System by Single Pneumatic Element

Abstract

In the previous paper the characteristics of the single pneumatic element was described.
This paper presents the results of the experimental investigation on the characteristics of the hydraulic element and on those of the control system.
The results of the frequency response experiments are shown by the Bode diagrams and then the stability of this control system is discussed.
Finally the errors of the actual cutting condition by this method are considered.
