Training Course - An Introduction to Closed Loop Control

A poorly controlled test system may yield poor results or take longer to complete a test than is necessary. Understanding the mechanics of your system control will greatly enhance your ability to operate a testing machine safely and efficiently and could result in performance improvements.

This two-day course covers a comprehensive introduction to closed loop control and is ideal for technical staff involved in fluid power motion control.

Course objectives

• Provide a core understanding of closed loop control
• Inform participants about open and closed loop systems
• Review feedback, error and control modes, and safe operation
• Understand the link between electronics and hydraulics
• Gain a core glossary of terms used within closed loop control

Who should attend this course?

• Anyone new to working with or around hydraulic equipment
• Anyone regularly working on hydraulic equipment and running multiple different tests
• Anyone managing testing staff or programmes and would benefit from an overview of closed loop control and devices
• Anyone seeking to refresh their knowledge of system control

Course content

• Definition of a servomechanism
• Electrohydraulic proportional control systems (Power source, control element, feedback sensor, error activator)
• Servo and proportional valves (including three stage valves if required).
• Feedback sensors - position, force and pressure etc. (including Rcal. and calibration)
• The error activator - the error path
• The application of the basic elements in a closed loop control system
• Step response - marginally stable criteria (include three stage valves if required)
• Electronics - amplifiers - proportional, integrating, differential and damping (PID)
• Digital vs. analogue electronics
• Control modes
• Dither and servo-valve balance
• Glossary of terms

Course presenter:
Mr Stephen Barrett MIET MRAeS, General Manager – ZwickRoell Motion Control & Servo Hydraulic Division.
Stephen Barrett has a wealth of experience in monotonic and dynamic servo hydraulic testing systems spanning more than 50 years.

Participants will receive comprehensive training course notes and a training course completion certificate. Lunch will be provided.
