Sliding Mode Control Based Piezoelectric Actuator Control
In this paper a method for piezoelectric stack actuator control is proposed. In addition a brief discussion about the usage of the same methods for estimation of external force acting to the actuator in contact with environment is made. The method uses sliding mode framework to design both the observer and the controller based on an electromechanical lumped model of the piezoelectric actuator. ...
متن کاملTracking control of piezoelectric actuator using adaptive model.
Piezoelectric actuators (PEAs) have been widely used in micro- and nanopositioning applications due to their fine resolution, rapid responses, and large actuating forces. However, a major deficiency of PEAs is that their accuracy is seriously limited by hysteresis. This paper presents adaptive model predictive control technique for reducing hysteresis in PEAs based on autoregressive exogenous m...
متن کاملTracking control of piezoelectric actuator system using inverse hysteresis model
The intrinsic hysteresis behavior of piezoelectric material limits the tracking control accuracy of the actuators. This paper describes a tracking control method for piezoelectric actuators based on the combination of feedforward and feedback loops. The hysteresis of piezoelectric actuators is linearized in feedforward loop with an inverse hysteresis model based on a neural network. The number ...
متن کاملDevelopment of Piezoelectric Actuator Control System using FEM
In this paper, the Finite Element Method (FEM) is proposed for application to a real-time control system of connected piezoelectric actuators, assuming an actuator as finite elements, which are mainly used in the field of computational mechanics. The FEM is capable of expressing the state of an entire system by stiffness equations, and can cope flexibly with lack or disability of constituent el...
متن کاملForce-deflection behavior of piezoelectric C-block actuator arrays
C-blocks are unique piezoelectric building blocks which can be combined in series or parallel to generate tailorable performance and exploit the advantages of bender and stack architectures. This paper presents a complete theoretical model that predicts the force-deflection behavior for any generic C-block actuator array configuration. An experimental investigation with five case studies is des...
