Fuzzy Control System Development Tools Based On Industrial PC

Fuzzy logic control has recently proved to be a successful control approach for complex nonlinear , large delay, multivariab, uncertainty systems which needn't construct the controlled object's mathematic model, just considers locale operator's experience and related expert's knowledge as control mechanism and strategy. The past few years have witnessed a rapid growth in the number and variety of applications of fuzzy logic, ranging from consumer products and industrial process control to medical instrumentation, information systems, and decision analysis.PC based system is a new direction for autoimmunization technique, for its characteristics such as low cost, open and good compatibility with IT technique. In this paper fuzzy control system development tools based on industrial PC, which named FCDS for short, is designed. Thedevelopment cycle for fuzzy control is significantly reduced based on FCDS so makes the fuzzy controller easy to implement.FCDS is based on windows environment and has friendly man-machine interface. Membership function editor, control rule editor,five fuzzy reasoning methods and three defuzzification methods are supplied. Back up the whole process in designing fuzzy controller. Especially it can integrately run with ForceControl and KingACT configuration software.The real-time fuzzy control respectively for the three-section electric furnace and three tank liquid level experiment equipment is carried out to show the effectiveness of the fuzzy controller designed by FCDS, in the mean while realize integrately run with ForceControl and KingACT configuration software. FCDS promotes fuzzy control to take a step toward the practice.
