High Performance Motion Tracking Control for Electronic Manufacturing

High Performance Motion Tracking Control for Electronic Manufacturing

Motion control requirements in electronic manufacturing demand both higher speeds and greater precision to accommodate continuously shrinking part/feature sizes and higher densities. However, improving both performance criteria simultaneously is difficult because of resonances that are inherent to the underlying positioning systems. This paper presents an experimental study of a feedforward con...

Lean Manufacturing for High Performance

Enhancement of Robust Tracking Performance via Switching Supervisory Adaptive Control

When the process is highly uncertain, even linear minimum phase systems must sacrifice desirable feedback control benefits to avoid an excessive ‘cost of feedback’, while preserving the robust stability. In this paper, the problem of supervisory based switching Quantitative Feedback Theory (QFT) control is proposed for the control of highly uncertain plants. According to this strategy, the unce...

Information #ows for high-performance manufacturing

The successful implementation of many management best practices (just-in-time, total quality management, concurrent engineering, etc.) heavily depends on proper organisational communication and information management. In this paper, we address the issue of how these best practices, labelled as high-performance manufacturing (HPM) practices, can a!ect a "rm's communication structure. The paper "...

Adaptive robust motion control of linear motors for precision manufacturing

Linear motors offer several advantages over their rotary counterparts in many precision manufacturing applications requiring linear motion; linear motors can achieve a much higher speed and have the potential of gaining a higher load positioning accuracy due to the elimination of mechanical transmission mechanisms. However, these advantages are obtained at the expense of added difficulties in c...
