Design and tuning of fractional-order PID controllers for time-delayed processes [PDF]
, 2016 Frequency domain based design methods are investigated for the design and tuning of fractional-order PID for scalar applications. Since Ziegler-Nichol’s tuning rule and other algorithms cannot be applied directly to tuning of fractional-order controllers,
