Vector　time　series　autoregressive　moving　average　predictive　and　wavelet　neural　networks　PID　method　is　proposed　in　order　to　solve　the　requirement　of　optimal　parameters　real-time　calculation　in　various　control　fields　(engineering　systems,　economics　systems,　etc.),　especially　to　solve　the　instability　and　poor　control　performance　problem　of　control　parameters　online-tuning　in　engineering　practice.　Based　on　additional　wavelet　neural　networks　and　vector　autoregressive　moving　average　predict　method　and　comparative　experiments　of　relative　methods,　better　feasibility,　reliability,　speed,　lower　static　error,　more　flexible　parameter　adjustment　ability　are　verified.　©　2014　IEEE.
