In this paper, a multiple fault parameter identification method based on extremum seeking algorithm is proposed for the consensus of multi-agent systems. Firstly, a model for the cooperative consensus multi-agent systems is established based on the graph theory and linear system theory. Secondly, by using the proposed cooperative consensus model, an adaptive multiple fault parameter identification...
It is assumed that the network of cortical brain area associated with task difficulty may dynamically allocate resources for difficult decisions. As a result, it could play an indispensable role during the process of decision making. Recently, the lateralized readiness potential (LRP) is reinterpreted as a new way to study the evidence accumulation process during decision making. Therefore, we use...
Central heating system is a big lag, time-varying, nonlinear complex system, the parameter self-tuning fuzzy PID control can use the fuzzy control rules to modify the PID parameters online, and therefore has good adaptive ability. This paper analyzes the central heating system in the model, and designed a fuzzy parameter self-tuning PID controller. PID control and fuzzy PID control simulation of the...
Ellipse is an important feature curve usually used in image analysis, computer graphics and computer aided geometric design. In this paper, we propose a new ellipse fitting method using data normalization. Prior to the ellipse fitting, a linear normalization transformation is used to preprocess the original data. The normalization transformation can increase the computation stability in solving the...
Cubic Bezier surface is a popular surface used in geometry modeling and computer graphics. In this paper, we investigate the relationship between the triangular Bezier surface and the B-net, and analysis the convexity of cubic triangular Bezier surfaces. Some sufficient and necessary conditions for the convexity are obtained. These conditions are good for controlling the convexity in surface modeling.
This paper proposes a back-propagated network (BPN) and applies it to predict the rainfall using meteorological satellite data. In the case study, the back-propagated network (BPN) combining with SGji-Dao SM/I microwave frequency channels was employed to establish a suitable method for estimating rainfall at sea surface during typhoon periods. These results are then verified with the data from four...
Underwater vibration suction method (UVSM) is a novel suction strategy used in the water environment. Mimicing the suction mechanism of octopus, this method can improve the adsorptive capacity of a suction cup by making it vibrate against the wall in the water. In this paper, the fundamental principles of UVSM and its primary application are presented. First, the mathematic model of UVSM is built...
Network value has attracted more and more attentions from scholars and enterprisers. Information through network can essentially impact everyone, while everyone in the network has the structure function to the network and may also influence others. But the contribution to the network is not the same for every one. Based on the complex network theory and customer activity, a customer network value...
Society as a whole has been affected by Internet and e-commerce. This paper discusses the correlation between Internet and service trade based on the impact of the Internet users growth on service trade. In particular, we analyze the effect of different Internet user on service imports and exports through comparing the data from China, the United States and South Korea. This paper concludes three...
