This paper presents the modeling and control of a Flexure-Based Electromagnetic Linear Actuator (FELA) that is employed as a high-precision imprinting actuator of a desktop hot-embossing imprinter. In this work, a systematic approach of obtaining the unknown physical parameters of FELA is presented. Subsequently, these parameters are used to design two model-based PID controllers that allow the FELA...
Hot embossing process for thermoplastic polymers is one of the manufacturing technologies for microfluidics and optical components. It combines both micro-scale resolution and high throughput. This is a thermal process where a rigid stamp is pressed onto a polymer substrate so that micro-sized features or patterns can be replicated. PolyMethyl-MethAcrylate (PMMA) is one of the important engineering...
