【正文】 urnace. Software interrupt nested manner by two, higher efficiency. Because of limited memory chip is proposed, . normal control method of Kp mohan, adjust Ki, three parameters Kd, e to control. The resistance furnace temperature change system for second inertia pure inertial system, finally lag big respectively using PID algorithm and fuzzy control by MATLAB simulation of temperature control, puter got better control effect. While using the serial munication with the PC, written by vc puter interface, PC as PC for plex algorithm of choice and control.Keywords: SCM, temperature control, PID, matlab simulation
