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 AbidRoom # SE104, Ext: [email protected]://www.pieas.edu.pk/abid/CourseCourse Code and Title: EE435 Linear Control SystemsLevel: UndergraduatePrerequisite: Basic knowledge of Laplace Transform, Linear Algebra and Differential Equations, (PAM-225, PAM-242) Course Website: www.pieas.edu.pk/abid/index_files/LCS.htmCourse Material: Click here 31
