“…Coefficient of friction: A dry (Coulomb) friction model is assumed making the relationship between the (vertical) normal force (F n ) and the (tangential) friction force (F f ) (11) in which µ is defined as the coefficient of friction, and is the angle between the vertical direction M a n u s c r i p t 15 and the interaction force acting on the rotor. The at each collision is defined as the ratio of the tangential and vertical displacement of the stator at the tooth position.…”

“…Many piezoelectric motor models have been proposed; types of these models include: 1. Dynamic models based on nonlinear stator-rotor contact, without considering the reaction of the stator to contact with the rotor [15]; 2. Models based on the Rayleigh-Ritz assumed mode energy method, without considering shear and rotary inertia effects [16]; 3.…”

“…Accordingly, it is a nonlinear, time-varying and strong-coupling control system with a complex structure. Some paper [2,4] tried to deduce the theoretical model for USM and gained good results. However, except for the complicated mathematical derivation, systems with a high order number cannot be realized in practice.…”

Abstract. Considering the difficulty to build a proper model from theoretical derivation, system identification is being applied greatly in practical engineering. In this paper, specific to ultrasonic motor (USM), a practical and effective method of identify the structure and parameter is introduced. By fitting the curve of transient process of USM amplitude step for different orders, an effective method for estimate the transfer function is also introduced. Accordingly, the system with three orders should be applied in engineering. The paper provides a proper method to identify the model of USM. However, in terms of other types of execute components; a large number of experiments are requested as well.

Ultrasonic piezoelectric motor technology is an important system component in integrated mechatronics devices working on extreme operating conditions. Due to these constraints, robustness and performance of the control interfaces should be taken into account in the motor design. In this paper, we apply a new architecture for a fault tolerant control using Youla parameterization for an ultrasonic piezoelectric motor. The distinguished feature of proposed controller architecture is that it shows structurally how the controller design for performance and robustness may be done separately which has the potential to overcome the conflict between performance and robustness in the traditional feedback framework. A fault tolerant control architecture includes two parts: one part for performance and the other part for robustness. The controller design works in such a way that the feedback control system will be solely controlled by the proportional plus double-integral P I2 performance controller for a nominal model without disturbances and H∞ robustification controller will only be activated in the presence of the uncertainties or an external disturbances. The simulation results demonstrate the effectiveness of the proposed fault tolerant control architecture.
