A Fuzzy Control Strategy to Synchronize Fractional‐Order Nonlinear Systems Including Input Saturation

International Journal of Intelligent Systems, Volume 2023, Issue 1, 2023., 2023
One of the most important engineering problems, with numerous uses in the applied sciences, is the synchronization of chaos dynamical systems. This paper introduces a dynamic‐free T‐S fuzzy sliding mode control (TSFSMC) method for synchronizing the different chaotic fractional‐order (FO) systems, when there is input saturation.

A review of fault diagnosis, prognosis and health management for aircraft electromechanical actuators

IET Electric Power Applications, Volume 16, Issue 11, Page 1249-1272, November 2022., 2022
Abstract As More/All Electric Aircraft gradually become a research hotspot, electromechanical actuators (EMAs), which can directly convert electrical energy into mechanical energy, have gained more and more attention. However, since the reliability of EMA cannot meet the requirements of actual aircrafts, the practical application of EMA is severely ...

Lion swarm optimisation‐based tuning method for generalised predictive fractional‐order PI to control the speed of brushless direct current motor

IET Electric Power Applications, Volume 16, Issue 8, Page 879-895, August 2022., 2022
Abstract In order to enhance the speed tracking performance of brushless direct current motor (BLDCM), a new generalised predictive fractional‐order PI (GPFOPI) control algorithm ground on lion swarm optimisation (LSO‐GPFOPI) is proposed in this paper. First, GPFOPI combines robust generalised predictive control with scalable fractional‐order PI, whose

Analysis of voltage vectors and realization method of torque ripple reduction for BLDCM

IET Power Electronics, Volume 15, Issue 9, Page 865-876, 24 July 2022., 2022
Abstract BLDCMs are widely used in automotive, industrial and intelligent equipment fields due to their high power density, simple control, and good dynamic performance. However, its non‐sinusoidal characteristics have brought problems such as turn‐off phase freewheeling to the research and application of BLDCM DTC.
