Abstract: This paper states the principle and method of serial communication between personal computer and single chip microcomputer using MSComm communication control in VB6.0 in fiberglass mechanical temperature control system. It makes the parameters self-adaptation of PID controller possible by using of combined Fuzzy Logic Controller and PID, and the properties of PID controller have been perfected and the precision of controller
system has been improved. Besides, the combination of Fuzzy Logic Toolbox and SIMULINK are used to realize the simulation of this controller.
