This article addresses the security issue against data tampering attacks in identification of finite impulse response (FIR) systems with binary-valued observations. First, rate and estimation error caused by network attack are derived. From perspective attacker, it is investigated how to achieve maximum effect minimum energy. Second, compensation-type defense scheme designed. Under this, algorithm constructed, its strong convergence proved. Taking covariance matrix as performance index,...
In this review, we introduce the current state of art growth technology pure, lightly doped, and heavily doped (solid solution) nonlinear gallium selenide (GaSe) crystals that are able to generate broadband emission from near infrared (IR) (0.8 μm) through mid- far-IR (terahertz (THz)) ranges further into millimeter wave (5.64 mm) range. For first time, show appropriate doping is an efficient method controlling a range physical properties GaSe responsible for frequency conversion efficiency...
With the popularization and application of cyber–physical systems in many industry infrastructure fields, security issue has been quite an important concern. This article addresses defense problem against data tampering attack under framework system identification with binary-valued observations. From perspective attacker, it is shown that how to achieve maximum hit effect least energy. defender, a so-called compensation-oriented approach proposed, corresponding algorithm designed. The...
This paper reports a development of narrowband high-temperature superconducting filter with both high selectivity and flat group delay. The has center frequency 8.625 GHz 3-dB bandwidth 42 MHz (a fractional 0.49%). In order to achieve band-edge steepness excellent group-delay flatness, we introduce 14-resonator quasi-elliptic function response three pairs transmission zeros (one pair for two delay) in the cascaded quadruplet coupling structure. We also develop novel low radiation resonator...
This technical note studies the adaptive tracking control for a class of single parameter systems with binary-valued observations and time-varying thresholds. A projection algorithm is proposed identification, based on which an law designed via certainty equivalence principle. By use conditional expectation respect to estimates, it shown that identification both almost surely mean square convergent, closed-loop system stable, asymptotically optimal. numerical example given demonstrate...
Purpose This paper aims to propose an optimal control strategy based on the slip rate during tunnel footage process for cantilever boring robots. Design/methodology/approach A method combining adaptive dynamic programming and linear quadratic regulator is used solve torque, aiming achieve precise stable strategies. Findings The feasibility of proposed demonstrated through actual process. Comparative analysis with other methods further illustrates superiority this approach. Originality/value...

This technical note studies the adaptive control for linear systems with set-valued observations to track a given periodic target. Based on system parameters, accessorial parameters same order as that of tracking targets are introduced and estimated. Considering unknown can supply only limited information each time, two-scale algorithm is designed. Each input designed at large time scale lasts holding (small scale), during which parameter estimation constructed. From estimate signal updated...
