Although information and Internet technology developed rapidly, how to realize flexible integration of enterprise application, and how to realize coordination of the heterogeneous information system and automation of the business process, have been core issues that need to be further researched. Application of Web Services and WS-BPEL can solve this problem. By using Web Services, which is platform-independent...
Aiming at the problem that it is difficult to confirm the parameters of the PID controller and the parameters can not be changed once identified, an intelligent PID control method is proposed. According to the size of the system error, this algorithm controls the system with different subsections of different parameters, by using the particle swarm optimization (PSO) to optimize the parameters of...
This paper addresses the problem of non-stationary signal noise suppression, represents the conception of wavelet transformation and puts forward two kinds of measurements to evaluate the effectiveness of noise suppression. Comparison experiments for noise suppression are made using Fourier analysis and Wavelet analysis. Simulation result shows that Wavelet analysis is more suitable for non-stationary...
