In this paper, the distributed finite-time containment control problem for double-integrator multiagent systems with multiple leaders and external disturbances is discussed. In the presence of multiple dynamic leaders, by utilizing the homogeneous control technique, a distributed finite-time observe...

Robust control of a class of uncertain systems that have disturbances and uncertainties not satisfying "matching" condition is investigated in this paper via a disturbance observer based control (DOBC) approach. In the context of this paper, "matched" disturbances/uncertainties stand for the disturb...

<?Pub Dtl=""?> In this paper, the finite-time output feedback trajectory tracking control problem for autonomous underwater vehicles (AUVs) is investigated. The vehicle model is constructed in six degrees of freedom and the vehicle attitude is represented by quaternions to avoid representation singu...

Summary Nonlinear systems widely exist in real‐word applications and the research for these systems has enjoyed a long and fruitful history, including the system identification community. However, the modeling for nonlinear systems is often quite challenging and still remains many unresolved questio...

This paper explores the solution of using output feedback to stabilise a planar nonlinear model of a vertical take-off and landing (PVTOL) aircraft. We first construct a state feedback stabiliser by utilising the technique of finite-time convergent control. To address the lack of full state measurem...

A passive air sampling was conducted to measure polycyclic aromatic hydrocarbon (PAH) in ambient air of Imphal (urban), Thoubal (rural), and Waithou (mountain) of Manipur, Northeast India from January 2009 to December 2009. The mean PAH concentrations of urban air (235.6 ng/m3) were high compared to...

To improve the disturbance rejection property of permanent magnet syn- chronous motor (PMSM) speed control system, the integral sliding mode control (ISMC) method is introduced in the control design of speed loop. However, the simulation and implementation results show that it is difficult to balanc...

The rate of stigma exsertion is an important trait in rice breeding because the efficiency of hybrid rice seed production can be improved by increasing the percentage of stigmas that exsert. In this study, we developed a near isogenic line (NIL) from two parents, XieqingzaoB (XQZB) and Zhonghoi9308 ...

Leaf senescence, which affects plant growth and yield in rice, is an ideal target for crop improvement and remarkable advances have been made to identify the mechanism underlying this process. We have characterized an early senile mutant es5 (early leaf senescence 5) in rice exhibiting leaf yellowin...

An effective inverse design method is used to demonstrate an ultracompact and broadband silicon nitride Y-branch 3-dB power splitter. Its topology is determined by a continuously varying function inspired by the universal approximation theorem for neural networks. The proposed model ensures an adiab...

Grain size is one of the critical agronomic traits governing grain yield and quality in rice. However, the underlying genetic mechanisms that control grain size in rice are poorly understood. We used an introgression line derived from Zhonghui 8015 and Oryza rufipogon Griff. This introgression line ...

This paper concerns the perimeter control problem in the oversaturated region. The road network system is a nonlinear system. However, the existing achievements in the perimeter control setting are obtained by partially linearizing the system model around the point of interest, which is a local line...

In this study, a current sensorless sliding mode control (SMC) approach is proposed for a direct current–alternating current inverter system. The SMC scheme shows advantages in dealing with matched disturbances and model uncertainties. However, it fails to remove the effects of mismatched disturbanc...

The efficiency of hybrid rice seed production can be improved by increasing the percentage of exserted stigmas. To identify quantitative trait loci (QTLs) for this trait, we conducted QTL mapping using 75 chromosome segment substitution lines (CSSLs) developed from a cross between the donor parent, ...
