Matlab application for computer aided piezoelectric modelling
Description
This application was created on the basis of synthesis algorithm using Cauer method modified to work with electromechanical systems. It is a continuation of the ongoing research with an aim to create a working synthesis method for variable piezoelectric active damping and actuating systems. The application includes a synthesis module that allows the modelling of arbitrary piezoelectric cascade systems constrained on one side. The application also allows the analysis of the synthesised model to verify its response. The analysis module was created based on the matrix method for the second order differential equations of motion. The repository contains the main application file with the .mlapp extension and all prerequsite modules marked with .mlx extensions. It is necessary to have a working version of Matlab (the application was made with R2019b version) to access each file and application source code.

Steps to reproduce
This repository contains an application which was built upon multiple iterations of synthesis and analysis algorithms. The synthesis algorithm is based on the Cauer's method, modified to work with piezoelectric systems. The analysis method works on the basis of matrix method. There are also two material databases provided along with the application, which can be used for the synthesis process. To properly run the application, it is best to put all the underlying files into a single folder and run the Piezo_app.mlapp file. An interface should open up along with Matlab application. To synthesize a new model, a user has to first choose one of two available methods. The first method allows the synthesis of material properties based on provided geometrical dimensions of each piezoelectric element included in the model. The second method allows the synthesis of geometrical dimensions of each piezo element, based on provided material properties. Each model can be verified using the inbuilt analysis module. The module can be used to approximate the displacement graph in relation to frequency of the electrical current.
