Draw a Block Diagram for a closed-loop room temperature control system consisting of a space heater with a single control knob (0-100%) and a temperature sensor. Label significant dynamic blocks, inputs, outputs, and other variables. Briefly describe the importance of sensor dynamics (how quickly should it respond, how accurate should it be, etc.?), and disturbances (what types are likely to occur?). Briefly describe a simple, manual control strategy for keeping the room temperature near a constant setpoint (How would you manually regulate room temperature? Consider what you would do if the error was initially "large", and compare that to what you would do as the error became "small").
