A Model of Control Systems Theory Reference Input: Ideal value or goal state Comparator: Actual - Reference Action System Sensor: Detect Input Disturbance: Influences from outside the system Input: Values related to goal state 1/13/2022 Output: Results of the Systems actions
CST and the Themostat Reference Input: Thermostat = 72 o Comparator: 72 -65 = -7 Action System: Furnace is turned on Sensor: Thermometer at wall Disturbance: e. g. open window Input: Air temperature 65 o 1/13/2022 Output: Hot air is blown out of vents
CST and the Thermostat Reference Input: Thermostat = 72 o Comparator: 72 -73 = 1 Action System: Furnace is turned off Sensor: Thermometer at wall Disturbance: e. g. open window Input: Air temperature 73 o 1/13/2022 Output: No hot air
