Problems solved by technology

It is difficult to connect the actual sensing with the output, and for the PCR base, which needs to be in the 94°C-55°C-72°C three-temperature zone cycle temperature control system, due to its high precision requirements for temperature control, it is In actual control, the setting of its control algorithm parameters can no longer be adjusted by trial and error using conventional methods such as empirical method and attenuation curve method like general control systems.

Abstract

The invention relates to a parameter optimization method of a PCR pedestal temperature control system based on numerical simulation of a finite element model. The finite element model is generated in the finite element software COMSOL Multiphysics according to the designed manufacturing parameters of the finite element model of the PCR pedestal. The temperature control algorithm is designed on the base, and the optimized control parameters are obtained by joint debugging with MATLAB through the with MATLAB interface. The invention can greatly save time and material cost for the research and development of a new PCR base, and also provides a temperature dynamic and static performance test method for the design of more new control algorithms related to the temperature control of the PCR base.

Description

technical field [0001] The invention relates to the technical field of PCR base manufacturing design, in particular to a parameter optimization method of a PCR base temperature control system based on finite element model numerical simulation. Background technique [0002] Heat transfer performance is a central concern in PCR pedestal design. At present, in the design of the temperature control algorithm of PCR base, in addition to the accuracy and rapidity of its temperature, there is also the problem that the reaction model is difficult to be accurate, which makes the final temperature control performance unsatisfactory. Most of the existing simulation optimization design methods are aimed at the simulation of the temperature uniformity of the finite element model of the PCR base. It is difficult to connect the actual sensing with the output. For the PCR base, which requires a three-temperature cycle temperature control system of 94°C-55°C-72°C, due to its high accuracy r...
