The intelligence of controllers has increased over the decades. However, the number of applications of adaptive controllers is still restricted, due to practical limits of the implemented continuous adaptation. For processes which operate only in a limited number of modes (so called mode-switch processes), constant adaptation is not needed or desired. In this paper an intelligent extension of adaptive control will be presented, in which process behaviour can be stored in a memory, retrieved from it and evaluated for each mode of operation. This intelligent memory concept leads to an adaptive control structure which, after a learning phase, quickly adjusts the controller parameters based on retrieval of old information, without the need to relearn every time. This approach has been tested on a simulation model of an assembly robot, but it is directly applicable to many processes in the (petro)chemical industry.
Electrospinning is a method to produce polymer fibers from solution with diameters ranging from 100 to 500 nm. Pure Polyurethane was electrospun from solution to produce anisotropic fiber mat. The mechanical behavior ...

This book introduces the cutting-edge technology of micro/nano structure fabrication from precision machining, electrical discharge machining (EDM) and precision grinding and injection molding, the contents of the presented book includes but not limited to the machining process, cutting tool preparation, tool path generation, and surface evaluation. This book provides a variety of feasible fabrication methods and advanced manufacturing techniques for the precision fabrication of micro/nano-structures, especially for complex micro/nano-structures. Since the book focuses on the micro/nano-structure fabrication methods including hieratical micro/nano-structures, graduate students, engineering technicians, and researchers in related areas will benefit from this book; also, someone in related application fields such as biomedicine, communication, optics may be the potential readers of this book.
