Contact SupplierWe offer Relay Control System use full for control labs. In the present unit a simulated second order system is controlled by an electronic relay. Apart from a study of the relay characteristics the experiment introduces the concept of Describing Function. Finally the phase plane method of analysis is covered in detail where the switching trajectories can be displayed on an X-Y oscilloscope.
>>Highlights
System with electronic relay
Adjustable hysteresis and dead zone
Display phase plane diagram on CRO
Stability study by describing function method
>>Experiments
Study of the relay characteristics and display of the same on CRO for different values of hysteresis and dead zones.
Study of the effect of hysteresis on system stability. Graphical analysis to predict sustained oscillations.
