Energy storage systems (ESSs) can be applied to mitigate some of the negative impacts associated with a variable power generation source such as wind energy. The control ESS must accomplished over numerous time frames meet system objectives and respect capacity constraints. This paper proposes two-level structure for use wind-diesel system, which is suitable online implementation. developed coordinate delivered from two levels in order minimize diesel fuel consumption limit up/down rates...

This paper presents an application of H∞ and μ-synthesis controller design methods to a coal-fired power generation unit compares the closed-loop performance robustness control laws with those H2 law. The model which relates firing rate turbine valve position inputs throttle pressure megawatt outputs presented by Ollat Smoak in earlier work is modified match test data from Tennessee Valley Authority (TVA) unit. All three synthesis procedures are applied two-input two-output plant has time...

Finally, reducer’s decreased achieved ideal result.

The key issue of reducing software cost and improving reliability is locating defective codes precisely efficiently. In this paper, we propose a fault localization method which combines program slicing Bayesian method. First, perform dynamic according to the criteria. Then, calculate posterior probability Theory. Finally, take as suspicion degree statement rank statements in descending order based on degree. We apply our approach six open-source programs. results experiments show that can...

This paper discusses the design of a non-linear feed-forward PID controller based on control system smart cars. The resulting effectively solves contradiction between speed and stability linear controller. A simulation about traditional PID, is given to show that dramatically enhances both dynamic performance stability. Actual results also indicate car controlled by has good in speed.

AbstractThis paper proposes a Reconfigurable Mechanism for Application Control (RMAC) framework, which allows mapping mechanism into device driver direct control by an application like CAD/CAM. The RMAC paradigm is one of assigned to each class or model, can be used CAD/CAM process planner the mechanism. Under architecture, traditional M & G code language no longer necessary since motion entities (NURBS, lines, arcs, etc) passed directly through interface. design strategy using dynamic-link...

The hybrid active-passive fault-tolerant control (FTC) problem based on discrete event-triggered communication scheme (DETCS) is studied for nonlinear NCS (NNCS) with time-varying delay and any actuator failure.A T-S fuzzy model adopted to describe the fault of NNCS in which integration condition failure realized.Furthermore, by using appropriate constructed Lyapunov-Krasovskii function H ∞ theory, sufficient that ensure system possess integrality against possible failures deduced detection...

<title>Abstract</title> To solve the problem of environmental pollution from stockpiling solid waste and to achieve safe efficient underground engineering, an environment-friendly waste-based ternary geopolymer grout was developed using BFS, SSA, BRHA. KOH-activated grouts were used as controls. The applicability with different SSA additions also investigated. results showed that 28-day compressive strength SSA-activated reached 24.31 MPa, which exceeded control group by 163.7%. Potassium...
