Controlled variable in control system

WebFeedback control systems must be designed to suit a predetermined purpose. Normally, only the controller can be appropriately designed, whereas the process and the sensor are predetermined or constrained. Feedback control systems can be designed to achieve specific behavior of the output variable, for example: •.
