Piezoelectric Actuators: Vector Control Method

Piezoelectric Actuators: Vector Control Method: Base, Modeling and Mechatronic Design of Ultrasonic Devices guides researchers and engineers through the process of implementing the vector control method (VCM) in their systems. The book presents which measurements can be made, how to visualize a variable as a rotating vector, about the angular position of the rotating reference frame, how to calculate the parameters of the controllers, and how to observe key variables. Additionally, the book focuses on the modeling of PE ultrasonic transducers and investigates the energy conversion process in an ultrasonic transducer. - Presents the fundamentals of the VCM at a basic level for researchers and practitioners who are new to the field - Simulates several MATLAB and Simulink examples for deeper learning of the subject - Presents the application to several test cases, with actual measurements obtained on experimental test benches - Describes practical implementations of the method

FREDERIC GIRAUD is associate Professor at University of Lille and a member of the L2EP (Laboratory of Electrical Engineering and Power Electronics). He's teaching design of Mechatronic systems, with a focus on the electromagnetic actuators, the power electronics, the control theory, and the smart structures / smart material. His field of research deals with the modeling and the control of piezoelectric actuators in general. He developed the concept of the vector control for the position control of Traveling Wave Ultrasonic Motors, and extended it to Ultrasonic transducers in order to achieve high performances with vibrating devices. He is also a specialist in haptic devices. He develops new surfaces than can change how a user perceives them. He pioneered the 'ultrasonic tactile surfaces based on the ultrasonic vibration of a glass substrate, optimizing their design, improving their power efficiency, developing their control, and evaluating their performances through psychophysical studies. This research has lead to two new companies. He holds 4 patents, he authored and co-authored more than 60 papers in journal and conferences, and 2 book chapters. He's working with industrial partners through research contracts and projects, and has been involved in more than 6 national/international research projects (two as research leader) two of them are European projects."
