4. Present Simple in Context

Complete the paragraph with the correct Present Simple form of the verbs in parentheses:

In open loop control, the control action from the controller is (be) independent of the "process output" (or "controlled process variable"). A good example of this is (be) a central heating boiler controlled only by a timer, so that heat is (be) applied for a constant time, regardless of the temperature of the building. (The control action is (be) the switching on/off of the boiler. The process output is (be) the building temperature). In closed loop control, the control action from the controller is (be) dependent on the process output. In the case of the boiler analogy, this includes (include) a thermostat to monitor (monitor) the building temperature, and thereby feedback a signal to ensure (ensure) stability.
