Multivariable H∞ Control of the Thermoforming Reheat Process
نویسندگان
چکیده
The problem of closed-loop control during the thermoforming sheet reheat process is considered. The approach aims to improve the material distribution of a formed thermoplastic part via better sheet temperature control prior to forming. Improved control of material distribution will increase part quality and result in fewer part rejects, thereby increasing production efficiency. An in-cycle control strategy is proposed and the feasibility of in-cycle sheet reheat temperature control is examined based on simulation results for multivariable H∞ control.

Stability Analysis of a Closed-loop Thermoforming Reheat Process Using an Affine Quadratic Stability Test
Abstract: The process of manufacturing plastic parts by heating polymer sheets and forming them on a mold is called thermoforming. The heating stage of the thermoforming process is nonlinear and parameter-varying. The heater temperature set-points are usually determined by trial and error. A control design for this system can improve quality, reduce scrap and allow for temperature zoning. In th...
متن کاملFinite element analysis of the thermoforming of Polypropylene
Polypropylene (PP) is typically solid phase thermoformed at temperatures close to its crystalline melting point, usually in the 150° to 160° Celsius range. In such conditions the mechanical properties of the material rapidly decline with temperature and these large changes in properties make Polypropylene one of the more difficult materials to process by thermoforming. This paper presents the f...

A data-driven approach for optimizing the reheat process in a variable-air-volume box is presented. Data-mining algorithms derive temporal predictive models from the reheat process data. The biobjective model formed is solved with a modified particle swarm optimization algorithm. To increase computational efficiency, two levels of non-dominated solutions are introduced while solving the optimiz...
متن کاملRheological Modeling for Production of High Quality Polymeric
The fundamental defect inherent to the thermoforming technology is wall-thickness variation of the products due to inadequate thermal processing during production of polymer. A nonlinear viscoelastic rheological model is implemented for developing the process model. This model describes deformation process of a sheet in thermoforming process. Because of relaxation pause after plug-assist stage ...
