Food Screw Extruder many input and output parameters , the barrel temperature is controlled parameters important process in the extruder . Barrel temperature has a great impact on the yield and quality , as well as Extruder Extruder service life and operating safety . Food Screw Extruder control is a complex nonlinear system . Food Screw Extruder temperature detection and control the main topic addressed by analyzing the characteristics of the extruder , the overall design of the temperature control system , trying to design a suitable extruder temperature measurement and control system , in order to achieve the desired control effect . Based on the analysis of a variety of control algorithms , the use of engineering software MATLAB7.0 fuzzy immune PID control and conventional PID control simulation analysis to determine the fuzzy immune PID control algorithm as the temperature of the extruder prosecution ; hardware Sunplus SPCE061A MCU control of the core design of the signal acquisition circuit , keyboard circuit , display circuit and alarm control output circuit ; software is designed with a modular design, including the main program, sampling subroutine , keyboard handling routine control algorithm subroutine and control output subroutine. Food Screw Extruder the Sunplus SPCE061A microcontroller control core , on the basis of conventional PID control , the application of the principle of biological immune regulation , and fuzzy control theory , design fuzzy immune PID controller , real-time control of the extruder barrel temperature . This is conducive to the puffed -depth study of the theory and the development of puffed food , and to improve the yield and quality of the extruder to reduce energy loss , to ensure the production of safe , plays an important role . In addition, the system control algorithms , hardware design, programming for others with similar characteristics in the control system , a certain reference value .
