在研發的玻璃纖維機械爐溫控制系統中，本文使用VB6.0 的MSComm 控件來實現
PC 機與單片機之間的串行通信，并將模糊控制和常規PID 控制相結合，實現了PID 參數的在線自調整，提高了系統的控制精度。此外，用Fuzzy Logic Toolbox 和 SIMULINK 實現了對該控制系統的仿真。

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.
