Two-degree-of-freedom (2-dof) proportional-integral-derivative (PID) controllers are better than the 1-dof counterpart in the sense that the former can predominantly reduce large overshoot and ...

This paper proposes a design method for a robust fractional-order PID (FOPID) controller for time-delay systems. A new Bode's ideal transfer function is introduced to tolerance the time-delay in loop.
