In this paper, the diagnosis method based on wavelet and neural network is proposed. This method needs not to collect a large number of data, but simplifies the diagnostic process while ensuring the accuracy of diagnostic result. The three-phase stator current data were decomposed by db6 wavelet function. It does not require the introduction of additional detection equipment, but also avoid the intrusion...
In this paper, it first introduces the design of construction machinery system with common PID, and shows the shortcoming of the system with common PID, then discusses the design with the Fuzzy-PID. The three parameters (kp, ki, kd) are obtained by the Simulation software. At last, the results of common PID and Fuzzy-PID have been compared. The experiment which have be done have proved that Fuzzy-PID...
Increasing complexity of software engineering and expansion of scope of application makes software credibility be greatly questioned. How to complete high-quality software production more efficiently is a new software development issue. Data mining has been applied widely in knowledge discovery; data mining technology being used in software development process can not only enhances the accuracy and...
With the development of large scale integrated circuit technology and computer technology, that using a microprocessor as the core microcomputer of excitation thyristor converter will become the main development of thyristor converters in the future. This paper introduces the features of dsPIC30F6011, and focuses on the structure and function of the intelligent detection and control modules in the...
