Adaptive flight control for unmanned autonomous helicopter with external disturbance and actuator fault

open access: yesThe Journal of Engineering, 2019
A backstepping-based robust adaptive fault tolerant control (FTC) scheme is proposed for the altitude and attitude dynamic model of the medium-scale unmanned autonomous helicopter (UAH) subjected to external disturbance and actuator fault.

Decentralized robust load-frequency control synthesis in restructured power systems [PDF]

open access: yes, 2004
This dissertation is mainly focused on technical issues associated with load-frequency control (LFC) in restructured power systems. Operating the power system in the deregulated environment will certainly be more complex than in the past, due to the ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Fuzzy filtering‐based fault detection for a class of discrete‐time conic‐type nonlinear systems

open access: yesIET Signal Processing, 2021
The authors investigates the problem of fuzzy fault detection filter (FFDF) design for a class of discrete‐time conic‐type nonlinear systems. By applying Takagi–Sugeno fuzzy models, the conic‐type dynamic FFDF system is established.

PDV-based packet length allocation for networked control systems [PDF]

open access: yes, 2011
Networked control systems typically involve mul-tiple subsystems which share the communication network. In this system setting, besides the optimization of the quality of control of the considered networked control system, the efficient utilization of ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Comparing Controlled System Synthesis and Suppression Enforcement [PDF]

open access: yesInternational Journal on Software Tools for Technology Transfer, 2019
Runtime enforcement and control system synthesis are two verication techniques that automate the process of transforming an erroneous system into a valid one. As both techniques can modify the behaviour of a system to prevent erroneous executions, they are both ideal for ensuring safety.

Feature-space transform tying in unified acoustic-articulatory modelling of articulatory control of HMM-based speech synthesis [PDF]

open access: yes, 2011
In previous work, we have proposed a method to control the characteristics of synthetic speech flexibly by integrating articulatory features into hidden Markov model (HMM) based parametric speech synthesis.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
