| Abstract: | Industry control computer IPC,51 series MCU regulator,Kingview configuration software,KingACT software PLC,MCU assembly language and algorithm of minimum principle of optimum control are applied in the control of micro heating furnace.The method has been applied in the weighing system.Furthermore,the paper offers a way to control the blinking of the number LED display,enhance its brightness,strengthen I/O port's drive ability and its anti-interference,reduce the amount of wires to display the same signs in different places and thus make the whole process more operational.This paper discusses the structure of the system,the constructing of the mathematical model of object,how to test characteristic parameter of object on line by the upwards curve method,the minimum principle of optimum control and the realization of concrete algorithm. |
