Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

On generating correlated random variables with a given valid or invalid Correlation matrix [PDF]
In simulation we often have to generate correlated random variables by giving a reference intercorrelation matrix, R or Q. The matrix R is positive definite and a valid correlation matrix.

Mass matrix rules and the flat pattern of quarks
European Physical Journal C: Particles and FieldsSeeking mass patterns is a key to decoding the unknown flavor puzzles in particle physics. Inspired by quark hierarchical masses, the mass matrix can universally be factorized into a family-diagonal phase matrix $$K_L^q$$ K L q and a real symmetric ...

On q-Pell sequence spaces: A study of operator ideals and geometric properties
Kuwait Journal of ScienceThe matrix \( \mathcal{P}(q) = \{\Psi_{\lambda \mu}(q)\}_{\lambda, \mu \in \mathbb{N}} \), called the \( q \)-Pell matrix, with elements determined by \[ \mathcal{P}(q) = \begin{cases} \dfrac{2~q^{\mu-1}~\Psi{_\mu(q)}}{\Psi{_{\lambda+1}(q)}+\Psi{_ ...

New triangular q−Fibonacci matrix
In this study, we construct a new triangular q−analogue of the q−Fibonacci matrix˜fq =( fnk (q)) defined by ⎧ ⎪⎨ fnk (q) = ⎪⎩ qk fk (q), 1 ≤ k ≤ n fn+2 (q) − 1 0, otherwise. After, we use the analogue to define the sequence spaces c(f˜q), c0 (f˜q), ℓ∞ (f˜
