Analysis of Hydraulically Controlled Three-Point Link Hitch

Abstract

The dynamic analysis of the automatic control system with hydraulically controlled three-point link hitch were explained with using the Signal Flow Graph, and were mentioned the characteristics of hydraulic valve. It was very effective method to synthesize this system, because the values of the each element in this system could be considered separately.
In this link system, the internal resistance of hydraulic valve (four way valve) was important to stabilize the system. So, it was desirable to use the under-lap type hydraulic valve.
