Abstract:

In this paper, graphical programming language LabVIEW is regarded as the development platform, combining fuzzy logic module and PID control toolkit, designing a temperature control system. We can use Matlab Simulink to build simulation program, also can use the fuzzy logic module and simulation module of LabVIEW to build the simulation block of the system. Comparing with the PID control, the fuzzy-PID control is effective to improve the temperature of control system, the steady state capability and the steady state respond. As the curve shown, the effects of the fuzzy-PID control are analyzed. From above analysis, the period of design the fuzzy-PID controller is reduced. It has practical value for engineering.
