Simulation and Finite Element Files for "Design and Control of a Piezoelectric Microgripper for Micromanipulation of Biological Cells"
Year: 2026
Type: software
Abstract: This repository contains the computational files associated with the manuscript “Design and Control of a Piezoelectric Microgripper for Micromanipulation of Biological Cells.” The deposited materials include MATLAB/Simulink models used for the implementation and evaluation of the proposed control strategies, together with ANSYS Workbench project files used for finite-element analysis and design optimization of the compliant piezoelectric microgripper. The Simulink files include the force, impedance, and hybrid position/force control models, as well as the simulation cases used to evaluate nominal performance, tissue-stiffness uncertainty, mass-estimation uncertainty, sensor noise, piezoelectric hysteresis and creep, human embryonic stem cell manipulation, liquid-environment effects, and closed-loop bandwidth. Actuator voltage saturation and anti-windup are included in the relevant control models. The ANSYS files contain the parameterized Static Structural and Modal analyses used to evaluate displacement amplification, structural stiffness, stress, and natural frequencies, together with the optimization workflow based on AMOP and NLPQL. These files are provided to support the transparency and reproducibility of the simulation-based results reported in the manuscript.
