On the Use of Linear and Nonlinear Controls for Mechanical Systems Subjected to Friction-Induced Vibration

Friction-Induced Vibration and noisE (FIVE) is still a complex and nonlinear physical phenomenon which is characterized by the appearance of instabilities and self-sustained vibrations. This undesirable vibrational phenomenon is encountered in numerous industrial applications and can cause major fai...
