Consensus Tracking of Fractional-Order Multiagent Systems via Fractional-Order Iterative Learning Control [PDF]
Complexity, 2019 In this work, the consensus problem of fractional-order multiagent systems with the general linear model of fixed topology is studied. Both distributed PDα-type and Dα-type fractional-order iterative learning control (FOILC) algorithms are proposed. Here,

On Fractional-order PID Controllers [PDF]
IFAC-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.

Synchronization of Fractional-Order Hyperchaotic Systems via Fractional-Order Controllers [PDF]
Discrete Dynamics in Nature and Society, 2014 In this paper, the synchronization of fractional-order chaotic systems is studied and a new fractional-order controller for hyperchaos synchronization is presented based on the Lyapunov stability theory. The proposed synchronized method can be applied to an arbitrary four-dimensional fractional hyperchaotic system.

Fractional-order position/force robot control [PDF]
Second IEEE International Conference on Computational Cybernetics, 2004. ICCC 2004., 2005 This paper studies fractional-order (FO) position/force algorithms in the hybrid control (HC) and the cascade control (CC) of manipulators. The system performance is analyzed, in the time and frequency domains, and the effects of joint backlash and flexibility are investigated.

Fractional-Order Impedance Control for Robot Manipulator
Fractal and Fractional, 2022 Impedance control is an important method in robot–environment interaction. In traditional impedance control, the damping force is regarded as a linear viscoelastic model, which limits the description of the dynamic model of the impedance system to a ...
