A Novel Variable Step-Size LMS Algorithm for Process Controlling of Shale Gas Components Automation Detection

Shale gas is one of the clearest nature gases in the world. However, there are few reports about automation detection systems. In this paper, a variable step-size LMS (VSSLMS) is applied into process controlling of gas components detection. In order to analysis the regulation of gas controlling process, model of feedback signal is illustrated at first. Secondly, VSS-LMS algorithm is introduced to get a robust system with the feedback controlling. As a result, theoretical simulation and experiment are carried out to prove that VSS-LMS is of better performance than tradition algorithms.
