Description of the system to be simulated
The simulated system is a feedforward (plus feedback) control system for temperature control of a heat exchanger. The feedforward is from measured process liquid temperature. The feedforward controller is experimental, implemented as a table-lookup function.
Aim
The aim is to observe how adding feedforward control to the basic feedback control is improving the disturbance compensation of the control system.
Motivation
Disturbance compensation is the main task of most control systems.
Tasks
While adjusting the T_{in} temperature, try first feedback control and then add feedforward control. Is the control system performance improved with feedforward control?
