Theoretical efficiency limits for thermoradiative energy conversion
(Journal article; Peer reviewed, 2015)A new method to produce electricity from heat called thermoradiative energy conversion is analyzed. The method is based on sustaining a difference in the chemical potential for electron populations above and below an ... -
Robust decentralized adaptive neural control for a class of nonaffine nonlinear large-scale systems with unknown dead zones
(Journal article; Peer reviewed, 2014)The problem of robust decentralized adaptive neural stabilization control is investigated for a class of nonaffine nonlinear interconnected large-scale systems with unknown dead zones. In the controller design procedure, ... -
A parameter-dependent approach to observer-based H ∞ control for networked control LPV systems
(Journal article; Peer reviewed, 2014)We address the observer-based H ∞ controller design problem for networked control LPV (NC LPV) systems, which are network-based systems that depend on unknown but measurable time-varying parameters. According to the analysis ... -

Robust redundant input reliable tracking control for omnidirectional rehabilitative training walker
(Journal article; Peer reviewed, 2014)The problem of robust reliable tracking control on the omnidirectional rehabilitative training walker is examined. The new nonlinear redundant input method is proposed when one wheel actuator fault occurs. The aim of the ... -
Robust control for autonomous spacecraft evacuation with model uncertainty and upper bound of performance with constraints
(Journal article; Peer reviewed, 2014)This paper studies the problem of guaranteed cost control for spacecraft evacuation. The relative dynamic model is established based on Clohessy-Wiltshire (C-W) equations. The paper has taken parameter uncertainty, output ... -
A novel mathematical formula for retrieval algorithm
(Journal article; Peer reviewed, 2014)A method is proposed to retrieve mathematical formula in LaTeX documents. Firstly, we represent the retrieved mathematical formula by binary tree according to its LaTeX description, normalize the structure of the binary ... -
Transformation algorithm of dielectric response in time-frequency domain
(Journal article; Peer reviewed, 2014)A transformation algorithm of dielectric response from time domain to frequency domain is presented. In order to shorten measuring time of low or ultralow frequency dielectric response characteristics, the transformation ... -
The limiting efficiency of four-band cells revisited
(Journal article; Peer reviewed, 2014)The limiting theoretical efficiency of four-band solar cells is revisited. In previous work, researchers have looked at the theoretical efficiency of four band cells where the smallest of the three sub-band gaps is closest ... -
Attitude stabilization control of a quadrotor UAV by using backstepping approach
(Journal article; Peer reviewed, 2014)The modeling and attitude stabilization control problems of a four-rotor vertical takeoff and landing unmanned air vehicle (UAV) known as the quadrotor are investigated. The quadrotor's attitude is represented by the unit ... -
The finding and dynamic detection of opinion leaders in social network
(Journal article; Peer reviewed, 2014)It is valuable for the real world to find the opinion leaders. Because different data sources usually have different characteristics, there does not exist a standard algorithm to find and detect the opinion leaders in ... -
Recent advances in static output-feedback controller design with applications to vibration control of large structures
(Journal article; Peer reviewed, 2014)In this paper, we present a novel two-step strategy for static output-feedback controller design. In the first step, an optimal state-feedback controller is obtained by means of a linear matrix inequality (LMI) formulation. ... -
Residual generator-based controller design via process measurements
(Journal article; Peer reviewed, 2014)This paper deals with designing the controller of LTI system based on data-driven techniques. We propose a scheme embedding a residual generator into control loop based on realization of the Youla parameterization for ... -
Wind turbine pitch control and load mitigation using an l1 adaptive approach
(Journal article; Peer reviewed, 2014)We present an application of L1 adaptive output feedback control design to wind turbine collective pitch control and load mitigation. Our main objective is the design of an L1 output feedback controller without wind speed ... -
Robust H∞ filtering for networked control systems with markovian jumps and packet dropouts
