CONSTRUCTION OF A MODEL OF PIEZOACTUATOR CONSIDERING THE NON-RIGIDITY OF THE BASE
Annotation
A dynamic model of a piezoactuator is proposed, which accounts for the effect of non-rigidity of the base on the payload displacement. Application of the model makes it possible to evaluate the negative effect of deformations on the quality of the control system operation. The results obtained allow to perform parameter identification and system quality analysis using computer simulation tools. In the adopted scheme, provision is made for choosing measuring means of the system and, if necessary, correcting the control law to minimize the operating errors.
