About the book
Precision positioning is widely required in both scientific research and industrial application. Taking advantages of high resolution, rapid response and compact structure, piezoelectric actuators are widely employed for achieving precision positioning, for example, in the fields of precision machining and measurement, nanomechanical testing, atomic force microscope (AFM), micromanipulation, et al. To satisfy the increasing requirements in precision positioning, in the past ten years, great efforts had been made to improve the performances of piezoelectric actuators, and significant progress had been achieved. For example, more and more novel principles have been proposed to design piezoelectric actuators. With the development in driving principle, structure design and control strategy, the speed, positioning resolution/accuracy, loading capacity, working bandwidth and stroke of piezoelectric actuators have been significantly improved, which, on the other hand, further enhance their applications.
This book intends to provide a forum, presenting the achievement and development of piezoelectric actuators in the aspects of driving principle, structure design, dynamic modeling, motion control, and novel applications.
