25PlantThe physical layout of a plant is an intrinsic part of
control problems. Thus a control engineer needs to be familiar with
the "physics" of the process under study. This includes a
rudimentary knowledge of the basic energy balance, mass balance and
material flows in the system.26SensorsSensors are the eyes of
control enabling one to see what is going on. Indeed, one statement
that is sometimes made about control is:
If you can measure it, you can control it.
27ActuatorsOnce sensors are in place to report on the state of a
process, then the next issue is the ability to affect, or actuate,
the system in order to move the process from the current state to a
desired state28ControllerFinally, we come to the real heart of
control engineering i.e. the algorithms that connect the sensors to
the actuators. It is all to easy to underestimate this final aspect
of the problem.As a simple example from our everyday experience,
consider the problem of playing tennis at top international level.
One can readily accept that one needs good eye sight (sensors) and
strong muscles (actuators) to play tennis at this level, but these
attributes are not sufficient. Indeed eye-hand coordination (i.e.
control) is also crucial to success.
29In summary:
Sensors provide the eyes and actuators the muscle but control
science provides the finesse.30Course OutlineInstructorMuhammad
