Abstract:In this paer, an equivalent transfer function is derived for the adaptive feedforward vibration control based on adaptive filter, and by which the system stability is analyzed. At first, the controlled structure model is transformed into Z domain and the equivalent transfer function in Z domain is derived. Then the system stability and the influence of sample period, the order of filter, and reference signal on system stability is addressed. The yielded conclusions are useful for guiding the control system design and the selection of control system parameters.
Keywords:active  control  vibration      control  adaptive  filter  adaptive  control  feedforward  control
