LPV Robust Controller Design with Regional Pole Assignment for an Aero-Engine

open access: yesXibei Gongye Daxue Xuebao, 2019
The aerodynamic characteristics of aero-engine, which have a wide range of flight envelopes, vary drastically, so its controller is required to be able to adapt to a large range of parameter variations and have good robustness. To solve the above problem,

H∞ positive filter-based control for positive linear systems [PDF]

open access: yesArchives of Control Sciences
This paper deals with the design of a positive functional H∞ filter-based controller for positive linear systems subject to bounded energy disturbances. We propose a new approach to numerically compute the controller, which is obtained via a function of ...

Enhanced lower-limb motor imagery by kinesthetic illusion

open access: yesFrontiers in Neuroscience, 2023
Brain-computer interface (BCI) based on lower-limb motor imagery (LMI) enables hemiplegic patients to stand and walk independently. However, LMI ability is usually poor for BCI-illiterate (e.g., some stroke patients), limiting BCI performance. This study

Comparison of Lightning Detection Between the FY‐4A Lightning Mapping Imager and the ISS Lightning Imaging Sensor

open access: yesEarth and Space Science, 2021
The Lightning Mapping Imager (LMI) onboard Fengyun‐4A (FY‐4A) is the first Chinese lightning detection sensor in geostationary orbit. This study presents the lightning characteristics observed by the FY‐4A LMI in its first year, and then observations ...

Cycling-Based Synthesis of Robust Output Estimators for Uncertain LPTV Systems

open access: yesSICE Journal of Control, Measurement, and System Integration, 2019
This paper studies a method of designing robust output estimators for discrete-time linear periodically time-varying (LPTV) systems with uncertainties. The key idea is to use not the well-known lifting technique but that called cycling for dealing with ...

PFC design method for SAC based on the stability theorem of the descriptor system and frequency response fitting

open access: yesMechanical Engineering Journal, 2015
Simple adaptive control (SAC) is a control method that maintains control performance despite perturbations of a plant. However, there is a problem in that the vibratory output occurs in the transient response when SAC is applied to a vibration system ...

Sensor fault detection and isolation for a class of uncertain nonlinear system using sliding mode observers

open access: yesAutomatika, 2020
Quick and timely fault detection is of great importance in control systems reliability. Undetected faulty sensors could result in irreparable damages. Although fault detection and isolation (FDI) methods in control systems have received much attention in
