Design elements of a control system;

Define control objectives - operational objectives control system required to achieve; Ensure process stability, external disturbance suppression, optimizing plant economic performance.

Selecting measurements - variable measurements to monitor operational performance; primary variables for direct measurement and/or secondary variables upon which inference is derived

Select Manipulated variables / that which the controller must directly adjust to achieve process control

Select Control Configuration- Information structure used to connect available measurements to available manipulated variables. General configurations include Feedback control, Inferential control, feedforward control

Controller design: Control Law to be implemented by the controller is defined
