Hydraulic and electro-hydraulic servo-controls

This article uses the theory of linear servo-controls, described in the Automation section of the Industrial Computing treatise. The reader is invited to refer in particular to the articles :

• Deterministic systems and signals. Transforms and charts [R 7 010] ;

• Control chain principles [R 7 090] ;

• Typical control chains [R 7 100] ;

• Frequency study of continuous systems [R 7 170] .

In addition, in the treatise Industrial Computing, the article Hydraulic regulation [R 7 530] deals with a subject close to that of the present article.
