The Development Of The Industrial Sewing Machines Based On Fuzzy Control System

The Fuzzy-PID controller is designed in this dissertation after exhaustive discussion and investigation of computer control system of industrial sewing machine system,in order to make know that this controller is implemented in practice and can get a good result, The Fuzzy-PID controller and The traditional PID controller are simulated and compared. 80C196KC MCU(micro-chip computer) is designed as the core of system. the main language is C++, In the designation of system software, adopts the modular designing method, and makes full use of the functions what the MCU offers, such as A/D function, interrupt function, PWM function, and software timer function. As a result, the following subroutines are programmed: keyboard scanning, A/D sample, LED displaying, data computing and dealing, software timer and control modules.
