Stability analysis of a controller for a high power ultrasonic actuator.
High power ultrasonic transducers for medical surgery require closed loop regulation of operating frequency and amplitude. This is a tutorial design paper which provides a description of the fundamental component properties and the criteria which are required to drive a power ultrasonic transducer. In addition, a classical root locus system analysis of the regulator servo in conjunction with requirements for idealizing individual blocks is also provided.
