Ahome heating system can be controlled by a thermostat. identify two other feedback control systems that can be found in most residences. describing briefly how each control system works, identify the sensor, controller, and actuator (the means by which the manipulated variable is controlled). identify the controlled variable and manipulated variable in each case, as well as a potential disturbance (remember: disturbance variables are factors that are accounted for in overall mass or energy balances, not bizarre fantasy impacts).
