Using the input and output signal, the method can model the system, and can control the dynamical property of the system with the inverse transfer function of the controlled object as the controller.

This paper introduces how to use the optimum transfer function to design nuclear reactor power controller.

As to the problem of tuning PID-CCC controller parameters, Cross-coupling fuzzy self-tuning based on CETF (contouring error transfer function) is proposed, which is robust to the parameters of plants.
