Abstract
In this chapter, it is revealed that a disturbance observer-based control scheme is very effective in controlling integral processes with dead time. The controller can be designed to reject ramp disturbances, step disturbances, and even arbitrary disturbances. Only two parameters are left to tune when the plant model is available. 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 to compromise the disturbance response with robustness. This control scheme has a simple, clear, easy-to-design, and easy-to-implement structure.
