IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.ABSTRACT This study introduces stator currents‐based model reference adaptive system (MRAS) estimators that employ variable structured control (VSC) in the adaptation mechanism to enable the online estimation of stator resistance and permanent magnet (PM) flux in interior permanent magnet synchronous motors (IPMSMs).

Observer‐Based Active Fault‐Tolerant Sliding Mode Control for Fully‐Constrained CDPRs
IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.An active fault‐tolerant sliding mode control strategy is developed for cable‐driven parallel robots. It uses real‐time fault estimation and sliding mode control to handle actuator faults and maintain robust tracking performance. ABSTRACT This study introduces an active fault‐tolerant sliding mode control (AFTSMC), designed explicitly for fully ...

Zeros of the Hurwitz zeta function in the interval (0,1) [PDF]
, 2011 We first give a condition on the parameters $s,w$ under which the Hurwitz zeta function $\zeta(s,w)$ has no zeros and is actually negative. As a corollary we derive that it is nonzero for $w\geq 1$ and $s\in(0,1)$ and, as a particular instance, the known

Applicable Analysis and Discrete Mathematics, 2018 We present some new results on the simultaneous approximation with given accuracy, uniformly on compact subsets of the critical strip, of a collection of analytic functions by discrete shifts of the Riemann and periodic Hurwitz zeta-functions. We prove that the set of such shifts has a positive lower density.

Leaf-to-leaf distances and their moments in finite and infinite m-ary tree graphs [PDF]
, 2015 We study the leaf-to-leaf distances on full and complete m-ary graphs using a recursive approach. In our formulation, leaves are ordered along a line. We find explicit analytical formulae for the sum of all paths for arbitrary leaf-to-leaf distance r as

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.This study proposes a recursive hierarchical observer combining an extended Kalman filter, extended state observer and weighted least‐squares algorithm to accurately estimate the oxygen excess ratio in polymer electrolyte membrane fuel cells under challenging low‐current and noisy conditions.

Event‐Triggered Autonomous Synchronization of a Class of Heterogeneous Multi‐Agent Systems
IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.This paper studies autonomous synchronization in heterogeneous multi‐agent systems under event‐triggered communication with dual triggers. A novel event‐triggered control law is proposed to achieve both dynamics and state synchronization, and sufficient solvability conditions are derived.

A generalized limit theorem for the periodic Hurwitz zeta-function
Chebyshevskii sbornik, 2019 The paper deals with the periodic Hurwitz zeta function \(\zeta (s,a,\{ a_{n} \} )=\sum _{n=0}^{\infty }\frac{a_{n} }{(n+a)^{s} } \), \(a>0,\; Res>1\), where \(\{ a_{n} \} \)is a periodic sequence. The author proves a generalized limit theorem for this function.
