Aiming at the levelling precision, speed and stability of suspended access platform, this paper put forward a new adaptive fuzzy PID control levelling algorithm by fuzzy theory. The method is aided design by using the SIMULINK toolbox of MATLAB, and…

Existence of many different Operators in the new electricity has brought many challenges in the system operation and control to obtain minimum generation cost and security. With the growing demand of electricity in the competitive electricity market environment, one or…

This paper proposes a test method for process deadlock based on graph grammars through constructing process resource diagram. Through using the construction rules, it can construct and judge the validity of the process resource diagram. Through using the test rules,…

In this paper, we first investigate and contrast the features of energy detection and cyclostationary feature detection for spectrum sensing. Combining the advantages of both, we propose an adaptive two-stage sensing scheme which first performs spectrum sensing using an energy…

Due to the nonlinearity of brushless direct current (BLDC) motor, it is difficult to obtain satisfied control characteristics using proportional integral derivative (PID) controller. A novel adaptive fuzzy control method based on high performance speed control is proposed in this…

A simple and high-precision current-to-voltage (I/V) converter circuit for multimeters and oscillographs is presented in this paper. The I/V converter measures the electric current with  uA and nA selectable ranges in the frequency range from direct current to 1 MHz.…

An improved method of SVM-BPSO feature selection based on cloud model is proposed to solve the local deadlock problem of the current SVM-BPSO methods. This method uses the Wrapper evaluation strategy, making SVM as the classifier, BPSO algorithm is adopted…

A new distributed E-commerce architecture is put forward in the study, through the careful analysis of the existing shortcomings of the architecture of the present E-commerce system. The system integrates multi-commercial activities of E-commerce under the loose-coupled service programs so…

In order to improve the validity of electronic equipment condition monitoring, overcome the shortage of normal KPCA (Kernel Principal Component Analysis) and SVDD (Support Vector Data Description) monitoring model, a method on electronic equipment condition monitoring based on KPCA-EDA (KPCA-…
