Title: | Model independent control of lightly damped noise/vibration systems | Authors: | Yuan, J | Issue Date: | Jul-2008 | Source: | Journal of the Acoustical Society of America, July 2008, v. 124, no. 1, p. 241-246 | Abstract: | Feedforward control is a popular strategy of active noise/vibration control. In well-damped noise/vibration systems, path transfer functions from actuators to sensors can be modeled by finite impulse response (FIR) filters with negligible errors. It is possible to implement noninvasive model independent feedforward control by a recently proposed method called orthogonal adaptation. In lightly damped noise/vibration systems, however, path transfer functions have infinite impulse responses (IIRs) that cause difficulties in design and implementation of broadband feedforward controllers. A major source of difficulties is model error if IIR path transfer functions are approximated by FIR filters. In general, active control performance deteriorates as model error increases. In this study, a new method is proposed to design and implement model independent feedforward controllers for broadband in lightly damped noise/vibration systems. It is shown analytically that the proposed method is able to drive the convergence of a noninvasive model independent feedforward controller to improve broadband control in lightly damped noise/vibration systems. The controller is optimized in the minimum Hâ‚‚ norm sense. Experiment results are presented to verify the analytical results. | Keywords: | Acoustic variables control Control system analysis Control theory Convergence of numerical methods Feedforward control FIR filters Functions IIR filters Impulse response Military data processing Telecommunication systems Transfer functions Wave filters |
