Comparing the new punching machine driven by linear induction motor (LlM) with its traditional form, the new machine has many great advantages, such as, simple construction, small size and weight, low production cost, short production time, easy to control, low noise and considerable energy saving. This paper introduces basic construction of new punching machine, then the LIM and it's control system...
This paper presents results of multimodal vibration suppression of a smart flexible cantilever beam by using single piezoceramic actuator and a single sensor. Piezoceramics PZT (lead zirconate titanate) patches are surface-bonded on the beam and perform as actuator and sensor. System identification for the dynamics of the first three modes and model reduction techniques are employed to assist in control...
