Book Description
This book explores emerging methods and algorithms that enable precise control of micro-/nano-positioning systems. The text describes three control strategies: hysteresis-model-based feedforward control and hysteresis-model-free feedback control based on and free from state observation. Each paradigm receives dedicated attention within a particular part of the text. Readers are shown how to design, validate and apply a variety of new control approaches in micromanipulation: hysteresis modelling, discrete-time sliding-mode control and model-reference adaptive control. Experimental results are provided throughout and build up to a detailed treatment of practical applications in the fourth part of the book. The applications focus on control of piezoelectric grippers. Advanced Control of Piezoelectric Micro-/Nano-Positioning Systems will assist academic researchers and practising control and mechatronics engineers interested in suppressing sources of nonlinearity such as hysteresis and drift when combining position and force control of precision systems with piezoelectric actuation.

Book Description
The electromechanical model and the dynamic electromechanical drift model were applied to an existing design of a piezoelectric driven valveless micropump, where these models can be used as design tools for the physical design of micropumps to give the optimum flow rate or performance for high precision applications, such as biomedical dispensing devices. In addition, the inverse of the electromechanical model was developed and applied to the micropump design, where such a model can be used to obtain a desired input voltage for a prescribed flow rate. This model can be used as the framework to develop controllers for output flow rate and pressure regulation and control, potentially in both open loop and closed loop control. In this thesis first a simple resistor-capacitor (RC) model for PZT is presented. The model is used to assess the suitability of various models used throughout the literature. Piezoelectric actuators offer high stiffness, fast response times, high sensitivity, low wear and tear, and large force output. Unfortunately the electrical properties of lead zirconate titanate (PZT) changes significantly with an applied mechanical load disturbance and PZT suffers from hysteretic behaviour. In addition, piezoelectric actuators drift in open loop control. Therefore, in order to employ PZT actuators in high precision applications for improved regulation and control, and to achieve absolute positioning for long durations, models are required to characterize the behaviour of the material. An experimental test rig is developed and designed for the simultaneous application of an arbitrary input voltage and an arbitrary load to a PZT stack actuator test specimen. The test rig is used to develop and validate an electromechanical model for piezoelectric actuators, which accounts for hysteresis. The model also characterizes the coupled electromechanical effect of the sensing and actuating signals. In addition, a dynamic electromechanical model is developed to characterize the hysteresis and drift behaviour of PZT. The presented model closely captures the absolute output displacement of the PZT actuator to a variety of applied input voltage excitations.

Book Description
Piezoelectric actuators are proving to be a reliable solution for many engineering applications, ranging from micro-positioning (machine tools, optic devices or modern microscopes) to active control of structures. The main motivation of this work is to delve into models to represent the hysteretic behavior of piezoelectric actuators in order to apply them to the conception of controllers for such hysteretic systems. A general study of piezoelectric actuators is performed to later deal with the modeling of such actuators. Due to the high non-linear behavior observed, the problem of identifying and modeling the actuator requires a hysteresis model. The Bouc-Wen model has been chosen and investigations to identify its parameters and to validate the model have been undertaken. Once the system has been identified, a linear controller has been designed and implemented in a real platform, employing a Digital Signal Processor.

Book Description
Covering the complete design cycle of nanopositioning systems, this is the first comprehensive text on the topic. The book first introduces concepts associated with nanopositioning stages and outlines their application in such tasks as scanning probe microscopy, nanofabrication, data storage, cell surgery and precision optics. Piezoelectric transducers, employed ubiquitously in nanopositioning applications are then discussed in detail including practical considerations and constraints on transducer response. The reader is then given an overview of the types of nanopositioner before the text turns to the in-depth coverage of mechanical design including flexures, materials, manufacturing techniques, and electronics. This process is illustrated by the example of a high-speed serial-kinematic nanopositioner. Position sensors are then catalogued and described and the text then focuses on control. Several forms of control are treated: shunt control, feedback control, force feedback control and feedforward control (including an appreciation of iterative learning control). Performance issues are given importance as are problems limiting that performance such as hysteresis and noise which arise in the treatment of control and are then given chapter-length attention in their own right. The reader also learns about cost functions and other issues involved in command shaping, charge drives and electrical considerations. All concepts are demonstrated experimentally including by direct application to atomic force microscope imaging. Design, Modeling and Control of Nanopositioning Systems will be of interest to researchers in mechatronics generally and in control applied to atomic force microscopy and other nanopositioning applications. Microscope developers and mechanical designers of nanopositioning devices will find the text essential reading.
