Fractional‐order controllers for irrational systems [PDF]

open access: yesIET Control Theory & Applications, 2021
In this contribution, fractional‐order controllers of the type PDμ and PIλ are applied to a class of irrational transfer function models that appear in large‐scale systems, such as networks of mechanical/electrical elements and distributed parameter ...

Fractional Order Impedance Control [PDF]

open access: yesIEEE Access, 2020
This paper proposes a novel fractional order impedance control. In traditional impedance control model, the orders of inertia, damping, and stiffness are integers and the contact force can be reduced effectively to some extent in robots and manipulators.

On Fractional-order PID Controllers [PDF]

open access: yesIFAC-PapersOnLine, 2018
A new Fractional Order Proportional-Integral (FOPI) controller tuning method is proposed in this paper for process control systems. This is achieved by combining Biggest Log-modulus Tuning (BLT) method and Internal Model Control (IMC) method of designing conventional PID controllers to tuning FOPI controllers for multivariable processes.
