Cascade architecture for nonlinear control of transient and stationary regimes of friction-induced vibrations

This paper presents a new control approach for mitigating friction-induced vibration (FIV) issued from the mode-coupling mechanism. The key idea is to put friction system onto cascade of independent subsystems by using first-stage control. Then, second-stage defined and proven be much more efficient controlling both transient stationary regimes FIV. Asymptotic stabilization formally demonstrated whole scheme. Moreover, numerical simulations, it shown that performances closed-loop systems present an interesting robustness with respect parameter uncertainty saturation phenomenon which opens up promising practical perspectives proposed technique.
