| EXPERIMENTS |
- Study of the relay characteristics and display of the same on CRO
for different values of hysteresis and dead zones. Hysteresis and
dead zone of the built-in 3-position electronic relay are adjustable in
the range of 0-600mV and 0-500mV respectively. The transfer
characteristics and output of the relay under various settings,
provides insight into the relay performance.
- Study of the effect of hysteresis on system stability. Sustained
oscillations may occur in the system under various conditions,
especially where hysteresis is present. The amplitude and frequency
of such oscillations are predicted from a graphical analysis and then
verified experimentally on the unit.
- Phase plane analysis of relay control system for various values
of Hysterisis and Dead Zones. The nature of the singular point in the
phase plane diagram has importance in the stability studies of nonlinear
systems. Here the phase trajectory is viewed on the CRO and the
effect of changing hysteresis and dead zone observed
