Chatter is a kind of self-excited vibration which may occur in the milling process and has several negative effects such as poor surface quality and severe tool wear. This paper presents an active chatter control method based on H∞ almost disturbance decoupling problem with measurement feedback and with internal stability (H∞-ADDPMS) and piezoelectric stack actuators. First, a milling process model...
Vibration is the main factor influencing the stable operation of mechanical equipment. Malfunction in large mechanical equipment is always attributed to excessive vibration. Active control plays a key role in vibration optimization and secures the safe operation of mechanical equipment. However, the current active control methods mainly focus on optimization of local vibration characteristics. Few...
