Suppose you were a heating engineer and you wished to consider a house as a dynamic system. without a heater, the average temperature in the house would clearly vary over a 24-h period. what might you consider for inputs, outputs, and state variables for a simple dynamic model? how would you expand your model so that it would predict temperatures in several rooms of the house? how does the installation of a thermostatically controlled heater change your model?
