Prediction of limit cycle oscillations in piecewise linear systems with multiple piecewise nonlinearities

IET Control Theory & Applications, 2021
Mathematical modelings of many electric and mechanical systems involve piecewise linear system. Piecewise linear system can possess a periodic solution called a limit‐cycle oscillation (LCO), which can seriously undermine the system performance ...

Optimal feedback path selection for interconnected power systems using load frequency control strategy

IET Generation, Transmission & Distribution, 2021
The main goal of an interconnected power system is to transfer power from one area to another while the network frequency and tie‐line flow remain within the prescribed limits.

Fuzzy model‐based multi‐objective dynamic programming with modified particle swarm optimization approach for the balance control of bicycle robot

IET Control Theory & Applications, 2022
Existing studies for the balance control of unmanned bicycle robots only consider constant forward velocity and a single optimal objective that cannot be applied to the complex motion situation.

A graphical approach for controller design with desired stability margins for a DC–DC boost converter

IET Power Electronics, 2021
A novel graphical tuning method of PID controller for output voltage regulation of a DC–DC boost converter is proposed. The advantage of the presented method is that the desired robustness level in terms of gain and phase margins can be pre‐specified.

Variable gain switching exact differential observer‐based compensation control for servo system with backlash

IET Control Theory & Applications, 2021
This paper proposes a novel variable gain switching exact differential observer (SEDO) to deal with the state estimation of mechanical servo system with unknown backlash. In order to compensate unknown non‐linear backlash accurately, a switching backlash

Fault detection for asynchronous T–S fuzzy networked Markov jump systems with new event‐triggered scheme

IET Control Theory & Applications, 2021
In this article, an adaptive event‐triggered fault detection problem for the asynchronous Takagi–Sugeno fuzzy networked Markov jump systems is investigated based upon the time‐varying delays. The purpose of designing a fault detection filter is to detect
