Intelligent Computing Method of State Parameters for RGS Based on PSO-BP
摘要
Abstract
As a non-contact seal,using regulatable gas seal can improve the running stability in the process of service by the introduction of intelligent control system. But the existing calculation method has many shortcomings, such as cumbersome process of establishing the calculation model or consuming time of iterative calculation. This paper proposes a BP(Back Propagation) neural network method optimized by particle swarm algorithm(PSO), which conforms to the requirements of output accuracy and timeliness for the intelligent control system. This paper developed intelligent control procedure based on PSO-BP to control type sealing state parameter. Then optimized thresholds and weight value of neural network, and discussed impact on parameters of intelligent computing procedure such as the particle swarm population, hidden layer, and neurons several. Finally, set up the test system. The test results verified the accuracy of intelligent computing procedure of the regulatable gas seal parameters. The research realizes the intelligent control of RGS, improves anti-interference ability of RGS and contributes the large centrifugal compressor to the direction of wide working condition, high parameters, high efficiency and intelligence.关键词
