Traveling wave ultrasonic piezoelectric motor modelling for the control design of an Automatic Headlight Levelling System

Abstract

This work deals with some major aspects of ultrasonic traveling-wave piezoelectric motor modelling in the context of an automotive application. The aim here is to establish a proper model of this type of actuator, reflecting its behaviour. This work is a part of a larger study on the headlight automatic position control on vehicles conducted in the framework of the OpenLab “Electronics and Systems for Automotive” combining IMS laboratory and Stellantis company. The main complexity of this work is to create a proper simulator of this type of actuator, and discussing and simulating some of its behaviours, beyond what is commonly discussed in the literature, such as the direction inversion, and holding torque. Analyses are conducted on various inputs to prepare the control design.
