document: Control of integral processes with dead-time . 1 . Disturbance observer-based 2 DOF control scheme A disturbance observer-based control scheme -LRB- a version of 2 DOF internal model control -RRB- which is very effective in controlling integral processes with dead time is presented . The controller can be designed to reject ramp disturbances as well as step disturbances and even arbitrary disturbances . When the plant model is available only two parameters are left to tune . One is the time constant of the set-point response and the other is the time constant of the disturbance response . The latter is tuned according to the compromise between disturbance response and robustness . This control scheme has a simple , clear , easy-to-design , easy-to-implement structure and good performance . It is compared to the best results -LRB- so far -RRB- using some simulation examples
