Nothing comes from doing nothing.
Prior to attempting this workshop, you should review Chapters 3 and 4 in the book.
The previous workshop introduced the concepts of capacitance and attenuation. These are ‘natural’ characteristics of a system, as are dead time and the process time constant. Now that we have a basic understanding of the way processes behave, we can apply this knowledge to control the process response.
Once the process personality is understood, we can manipulate process flows to maintain a desired variable at constant conditions, which are called set points. This is known as feedback control, where the value of a variable is ‘fed back’ to a controller which manipulates another variable according to the difference between the controlled variable and its set point.
