Aims & Learning Objectives:
To provide the basic groundwork in control theory and its application for the evaluation of electrohydraulic systems.
After taking this unit the student should be able to:
Design and predict the behaviour of practical control systems involving hydraulic actuation. Analyse the stability and apply compensation of such systems.
Content:
System Analysis: Simple valve controlled actuator, First order system, Block diagrams, Frequency response, Effect of fluid compressibility and load inertia on the valve controlled actuator, Codas control systems software.
Stability: Nyquist criterion, Bode plot, Nichols chart, Compensation.
Hydraulic Equipment: Electrohydraulic valves, Pump controlled systems.
