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.

Gap‐Loop Active Disturbance Rejection Control: Design and Experimental Validation for High‐Speed Maglev Train Guidance Systems

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
In high‐speed maglev trains, the active guidance system is responsible for centring the vehicle relative to the track, a function that becomes critical under centrifugal forces, crosswinds, and track irregularities. To address the limitations of existing control methods in multi‐disturbance environments, this paper proposes a gap‐loop active ...

Sliding‐Mode Control of Electromagnetic Suspension Systems Considering Disturbance Compensation

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study proposes an integrated control strategy for magnetic levitation systems, combining a cascaded linear extended state observer with an improved sliding‐mode control. This method accurately estimates and compensates for disturbances, significantly enhancing suspension stability and rejection capability.

A Nonstationary Geometry‐Based Model for Channel Characterisation in Vactrains Scenarios Using Leaky Coaxial Cables

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
In this paper, a 3D multi‐source GBSM model is proposed for the vacuum tube scenario using LCX. By equating the periodic slots to multiple magnetic dipole antennas, the electric field distribution of LCX is deduced, and the CIR expression is derived. Based on this, the multi‐link spatial‐temporal correlations, including the spatial CCF and temporal ACF,

A Multi‐Objective Optimal Synchronous Modulation Strategy for Three‐Level Converter Through Switching Angle Regulation

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a novel power loss reduction PWM (PLRPWM) strategy for three‐level neutral point clamped inverters. The proposed strategy aims to achieve multi‐objective optimisation by balancing low output harmonics, reduced switching losses and a balanced neutral‐point potential. ABSTRACT Three‐level neutral point clamped (3L‐NPC) converters have
