It is the first report about fault-tolerant-based prescribed performance control of switched nonlinear systems under multiple faults. The concerned faults include not only external …
This paper investigates the adaptive tracking control problem of a class of nonlinear systems with intermittent actuator faults and prescribed performance. In the backstepping …
Sketch-based image retrieval is an important research topic in the field of image processing. Hand-drawn sketches consist only of contour lines, and lack detailed information such …
For a class of stochastic nonlinear systems, this paper proposes a novel event-triggered adaptive control scheme by means of multi-dimensional Taylor network (MTN) approach for the …
As important atmospheric circulation patterns in Northern Hemisphere(NH), the North Atlantic Oscillation(NAO) and the Western Pacific teleconnection(WP) affect the winter climate …
海洋沉积物粒度研究对解析人类活动的环境影响具有重要意义，为提升沉积物粒度光谱分类精度，提出一种主成分分析（PCA）与连续投影算法（SPA）融合的特征提取方法（FOPAS），综合两种算法优势，丰富特征波长信息，剔除无关干扰的同时最大限度保留有效特征。以青岛东大洋村潮间带32份表层沉积物为研究对象，按0.3~0.2 mm、0.2~0.1 mm、0.1~0.075 …
Steady-state hydroelastic waves generated by a moving load with a uniform current are investigated analytically in the framework of nonlinear potential theory. Considering the load …
In this paper, the adaptive fault-tolerant control (FTC) problem is addressed for the stochastic nonlinear systems with multiple faults. The multiple faults, including the actuator …
北斗一代和北斗二代短报文每次通信数据长度只有78个字节,每次通信后间隔60秒或者300秒才能进行下一次通信,远远满足不了海洋观测实时通信的需求。设计了一套基于北斗短报文的海洋观测实时通信系统,北斗多卡机作为数据发送端,采用哈夫曼压缩算法将观测数据压缩后分成多个数据包,通过多个北斗卡分别发送,岸站接收系统接收到分包的数据后,将接收的数据包解压缩并整合成完整的观 …
针对飞行器纵向模型的不确定性参数和随机干扰，研究了一类飞行器航迹倾角的自适应跟踪控制问题。 在控制器设计过程中，将多维泰勒网(multidimensional Taylor network, MTN)的逼近特性和自适应backstepping方法相结合， 利用MTN网络逼近未知光滑非线性函数，提出了一种新的自适应MTN控制方法。通过Lyapunov稳定性理论 …
