An Optimized Fractional-Order PID Horizontal Vibration Control Approach for a High-Speed Elevator

Applied Sciences, 2023
Due to factors such as uneven guide rails and airflow disturbance in the hoistway, high-speed elevators may experience significant vibrations during operation. This paper proposes an optimized fractional-order PID (FOPID) method to suppress vibrations of

Electrothermal Twisted and Coiled Polymer Artificial Muscles and Their Applications in Soft Robotics

Small Structures, Volume 7, Issue 5, May 2026.
Researchers develop a PE@SPN electrothermal polymer artificial muscle with a parallel‐stranded spiral structure. A temperature self‐sensing‐driven hierarchical closed‐loop fractional order PID (FOPID) control scheme is adopted. A rehabilitation manipulator was designed, and subsequently, a series of experiments are conducted to test the performance of ...

Improving the Characteristics of the Direct FOC Strategy in DFIG‐Based Wind Turbine Systems Using FOIDD and FOPD Controllers

Energy Science &Engineering, Volume 14, Issue 2, Page 999-1021, February 2026.
This study presents a new control strategy for doubly fed induction generator (DFIG) wind turbine systems to overcome the limitations of traditional direct field control using proportional‐integral (DFOC‐PI) regulators, which are sensitive to coefficient changes and lead to low power quality.

Fractional‐order controller tuning via minimization of integral of time‐weighted absolute error without multiple closed‐loop tests

Asian Journal of Control, Volume 28, Issue 1, Page 20-33, January 2026.
Abstract This study presents a non‐iterative tuning technique for a linear fractional‐order (FO) controller, based on the integral of the time‐weighted absolute error (ITAE) criterion. Minimizing the ITAE is a traditional approach for tuning FO controllers. This technique reduces the over/undershoot and suppresses the steady‐state error. In contrast to

Design of Novel Exponential PDN Controller via Quadratic Interpolation Optimiser for Nonlinear and Unstable Ball and Beam System

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This study presents a novel exponential proportional‐derivative controller with filter (exp‐PDN) for stabilising the nonlinear and underactuated ball and beam system. Unlike conventional PID‐based approaches, the proposed controller removes the integral term, resulting in faster transient responses and improved robustness.

A Novel Model‐Free Defense Scheme for Power Systems Stability Under Cyber Attacks

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper studies the load frequency control performance of Kundur's 4‐unit‐12‐bus power system under the frequency signal manipulated by false data injection attacks. In this regard, a model‐free resilient defence strategy, comprising a model‐free detection scheme and an event‐triggered mechanism, is proposed to encounter these attacks.
