Precision Motion Control

Applications of precision engineering, generally defined as manufacturing to tolerances that are better than one part in 105, abound and can be found in various semiconductor processes (e.g., lithography, wafer probing, inspection), co-ordinate measuring machines, precision metrology systems (e.g., scanning probe microscopy), and robot/machine tools to carry out micro-assembly (e.g., micro-electro-mechanical systems) and delicate short-wavelength laser processes.Precision Motion Control (second edition) focuses on enabling technologies for precision engineering - issues of direct importance to be addressed in the overall system design and realization: precision instrumentation and measurement, geometrical calibration and compensation, and motion control. It is a compilation of the most important results and publications from a major project that develops a state-of-the-art, high-speed, ultra-precision robotic system.The second edition has been extensively edited and rewritten throughout with the following particular areas being expanded or added:? piezoelectric actuators;? fine movement control;? gantry-stage control;? interpolation of quadrature encoder signals;? geometrical error modelling for single-, dual- and general-XY-axis stages.By providing detailed experimental verifications of the material developed, a comprehensive and thorough treatment of the subject matter is provided in a manner that is accessible to a broad base of readers, ranging from academics to practitioners. Praise for the first edition:?a refreshing and much needed addition to the field of precision engineering? well written, readable, and concise yet comprehensive.                                                  International Journal of Robust and Nonlinear Control?an excellent single source of essential topics related to precision motion control.                                                                                              Applied Mechanics Reviews Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.
