Information

Model representing a voltage controller that unplugs a load when its voltage is outside of the accepted thresholds.

The model contains a finite state machine controller that detects voltage deviations. If the voltage input V exceeds the nominal value V_nominal by more than 1+V_tr then the control signal y becomes zero for a period t = tDelay. If after this period the voltage is still higher than the thresholds the output remains equal to zero. The model has a parameter T that represents the time constant associated to the electrical switch. This time constant is used to parametrize a first order filter that represents such a dynamic effect. The presence of the first order filter avoids that the output of the finite state machine controller are differentiated (causing runtime errors).
