6. Namely, the device measures the temperature in a building, compares that temperature to a desired set point, and uses the “feedback error” between these two to operate the heating plant, e.g., to turn heating on when the temperature is too low and to turn if off when temperature is too high.

4. Optimal control theory gave precise conditions under which a controller minimized a given cost function, either as an open loop input (such as computing the thrust for optimal trajectory generation) or as a closed loop feedback law.
