Detecting Nonlinear Oscillations in Process Control Loop Based on an Improved VMD

A novel detector based on improved variational mode decomposition (VMD) is proposed to detect the nonlinearity-induced oscillations. Despite its high adaptivity and frequency resolution, the effectiveness of VMD highly depends on parameters, including mode number K, initial center frequency &#x0...
