a 1.1 Which of the following statements are true? (a) Feedback and feedforward control both require a mea- sured variable. (b) The process variable to be controlled is measured in feedback control. (c) Feedforward control can be perfect in the theoretical sense that the controller can take action via the manipulated variable even while the controlled variable remains equal to its desired value. (d) Feedforward control can provide perfect control; that is, the output can be kept at its desired value, even with an im- perfect process model. (e) Feedback control will always take action regardless of the accuracy of any process model that was used to design it and the source of a disturbance. contains both the measuring element and the controller. The furnace is either on (heating) or off. Draw a schematic diagram for this control system. On your diagram, identify the controlled variables, manipulated variables, and disturbance variables. Be sure to include several possible sources of disturbances that can affect room temperature. 1.3 In addition to a thermostatically operated home heat- ing system, identify two other feedback control systems that can be found in most residences. Describe briefly how each of them works, include sensor, actuator, and controller information. 1.4 Does a typical microwave oven utilize feedback control to set cooking temperature or to determine if the food is "cooked? If not, what mechanism is used? Can you think of any disadvantages to this approach, for example, in thawing and cooking foods? 1.2 Consider a home heating system consisting of a natural gas-fired furnace and a thermostat. In this case the process consists of the interior space to be heated. The thermostat a 1.5 Driving an automobile safely requires a large amount of individual skill .
