Abstract

Piezoelectric ultrasonic transducers are widely used and can offer great benefits, e.g., in ultrasonic machining, cleaning, and cutting. However, due to the resonance behavior of these transducers, feedback controllers that track the resonance frequency and regulate the vibration amplitude are often indispensable to ensure efficiency. This article presents a generic and efficient approach to designing proportional–integral controllers for piezoelectric ultrasonic transducers using the method of pole-zero cancellation based on a model of their vibration amplitude and phase dynamics. The parametric design method was experimentally applied to a piezoelectric ultrasonic periodontal scaler and compared with other tuning methods to demonstrate its advantages. The parametric design methodrequired ten times fewer experiments to parameterize the controller than the Ziegler–Nichols method, for instance, and resulted in a closed-loop system with better load rejection than the other tuning methods. The results document that the new method can considerably simplify and accelerate the development of performant feedback controllers for piezoelectric ultrasonic transducers.

期刊介绍： Mechatronics is the synergistic combination of precision mechanical engineering, electronic control and systems thinking in the design of products and manufacturing processes. It relates to the design of systems, devices and products aimed at achieving an optimal balance between basic mechanical structure and its overall control. The purpose of this journal is to provide rapid publication of topical papers featuring practical developments in mechatronics. It will cover a wide range of application areas including consumer product design, instrumentation, manufacturing methods, computer integration and process and device control, and will attract a readership from across the industrial and academic research spectrum. Particular importance will be attached to aspects of innovation in mechatronics design philosophy which illustrate the benefits obtainable by an a priori integration of functionality with embedded microprocessor control. A major item will be the design of machines, devices and systems possessing a degree of computer based intelligence. The journal seeks to publish research progress in this field with an emphasis on the applied rather than the theoretical. It will also serve the dual role of bringing greater recognition to this important area of engineering.
