Methods The review evaluates mathematical models in tear film dynamics and their limitations, discusses contact lens wear models, and highlights computational mechanical models. It also explores computational techniques, customization of models based on individual blinking dynamics, and non-invasive diagnostic tools like high-speed cameras and advanced imaging technologies. Results Mathematical models provide insights into tear film dynamics but face challenges due to simplifications. Contact lens wear models reveal complex ocular physiology and design aspects, aiding in lens development. Computational mechanical models explore eye biomechanics, often integrating tear film dynamics into a Multiphysics framework. While different computational techniques have their advantages and disadvantages, non-invasive tools like OCT and thermal imaging play a crucial role in customizing these Multiphysics models, particularly for contact lens wearers. Conclusion Recent advancements in mathematical modeling and non-invasive tools have revolutionized ocular health research, enabling personalized approaches. The review underscores the importance of interdisciplinary exploration in the Multiphysics approach involving tear film dynamics and biomechanics for contact lens wearers, promoting advancements in eye care and broader ocular health research.

The second chapter describes the equipment with which we work throughout the project, consisting of two rotary brushed DC motors provided by the company Ingenia Motion Control. The third chapter describes various techniques of system identification that are used to characterize the motor dynamics, and applied to the motors provided by the company Ingenia Motion Control. And the final chapter covers the design of controllers plants based on the specification in bandwidth, and provides detailed structures of PID control and I-PD control. This master thesis has been developed in the Institut de Robotica i Informatica Industrial (IRI) and in the company Ingenia Motion Control in the Firmware Division with the supervision of Vicenc Puig ...
