Accurate generation prediction at multiple time-steps is of paramount importance for reliable and economical operation wind farms. This study proposed a novel algorithmic solution using various forms machine learning techniques in hybrid manner, including phase space reconstruction (PSR), input variable selection (IVS), K-means clustering adaptive neuro-fuzzy inference system (ANFIS). The PSR technique transforms the historical time series into set phase-space variables combining with...

Due to the installation of different forms small-scale distributed generators (DGs), e.g. wind turbines, photovoltaic (PV) panels in domestic scope as well emergence real-time electricity pricing, achieving a cost-effective energy management through appropriately scheduling operation appliances becomes feasible. In this paper, we present an algorithmic solution aiming investigate potential economical benefits matching generation demand load control at level. Also pricing (RTP) scheme is...

The tank system is a typical model, which abstracted from water level in industry field. Generally it has the characters of time lags, non-linearity and difficult to making model building etc. For these reasons, traditional PID control sometimes canpsilat obtain content effects. This paper mostly adopts fuzzy controller fuzzy-PID system. By comparing results with PID, showed be better controller, both advantages control, possesses characteristics dynamic response higher stability.

The tank system is a typical industrial model, which abstracted from water level in process industry field. Generally it has the characters of time lags, non-linearity and difficult to build mathematics model etc. For some deviant problems often appeared during control system, this paper adopts fuzzy decision strategy deal with them. simulation effects controller show that responding quickly, small overshoot less static errors, practicably feasible area.

This paper exploits the network outer synchronization problem in a generic context for complex networks with nonlinear time-delay characteristics and nonidentical time-varying topological structures. Based on classic Lyapunov stability theory, criteria adaptive control strategy are presented, respectively, by adopting an appropriate Lyapunov-Krasovskii energy function convergence of system error can also be well proved. The existing results obtained giving certain conditions, example,...

For the issues of a long development cycle, poor portability and high-risk in process Zigbee wireless network, this paper introduces Unified Modeling Language (UML) to standardize process, improving efficiency ensuring product quality. According topological structure adopts module method design whole architecture with Rational Rose applies use case diagram, class sequence diagram state function model, model information activities finally completes system model. The results show that makes...

This paper looks into the outer synchronization issue of two networks with nonlinear, time-delay and different topological characteristics. Given general dynamic network models, a set criteria based on Lyapunov stability analysis are proposed theoretical is presented. In addition, to expand generality control criteria, schemes for linear coupling similar topologies derived respectively. Unlike existing solutions obtained from specific studies, scheme can be applicable class complex nonlinear...

The negative pressure of the thin powder storehouse can reflect working status cement ball mill on real time, which is system with characters serious non-linearity, multivariable and strong coupling etc. For fluctuate badly, this article introduces T-S fuzzy strategy to deal problems. From use in factory it shows, arithmetic bring benefit static effects realize control indirectly.

This paper exploits the outer synchronization between two dynamic networks with diversely varying node behaviours at presence of noise. Aiming to obtain a generic technical solution for network synchronization, problem is addressed scenarios non-identical topological structures, nonlinear inner coupling connections and time-delayed characteristics. The impact noise fully considered in theoretical performance analysis which makes derived criteria be able adopted practical engineering...
