“…The control signals u1 and u2 are saturated to maximal values equal to ±0.01 Volt. The corresponding displacements x1 and y3 are shown in Figure (14) while the non-saturated and saturated controls u1 and u2 are plotted in Figure (13). These results are obtained with the damping rates fixed to 0.7.…”

“…Most of the recorded studies about FIVs mitigating have focused on reducing or suppressing the amplitude of the steady vibration regardless of the properties of the corresponding transient regime such as the amplitude and the settling time. A more damped and fast transient is often paid by high amplitude for the control inputs which, not to mention the energy cost, leads to saturation phenomena [14,12]. This paper deals with this issue and proposes a new approach for mitigating both the mode-coupling based steady and transient friction-induced vibrations by considering minimal models representing mode-coupling instabilities occurring in friction systems as drum brake systems [22].…”

“…Some researchers (Thomson, 1999; Chatterjee et al, 2004; Sahoo and Chatterjee, 2020) have used high-frequency external excitations, while others (Chatterjee, 2007; Das and Mallik, 2006; Chatterjee and Mahata, 2009a, 2009b; Saha and Wahi, 2014) have utilized time-delay active feedback controllers to reduce friction-induced vibration. A nonlinear saturated relay proportional–derivative (PD) control (Zheng et al, 2019a, 2019b) is proposed for faster positioning of 1-DOF mechanical systems with friction and actuator saturation. The proposed control includes a relay position error for friction compensation and a saturated nonlinear function for faster transient with bounded input.…”
