Course description
Control of Electrohydraulic Systems
Our course contains two parts. In the first, you'll attend our Introduction to control of mechatronics systems. You'll then move on to concentrate on more advanced modelling and control strategies for electrohydraulic systems for the rest of the course.
At the end, you'll be able to predict the behaviour of electrohydraulic systems, determine a system’s frequency response and stability characteristics, and improve the steady state and dynamic response using appropriate compensation techniques.

Suitability - Who should attend?
Our course is for engineering professionals, system and control designers, software developers, and graduates. You should have a basic knowledge of mechatronic systems; in particular, those involving electrohydraulic and electromagnetic components. If you are new to this field, we recommend you take our introductory courses for hydraulics and electrical drives. You will also need good mathematical knowledge.
Outcome / Qualification etc.
