Abstract


Create a practical engineering environment laboratory for engineering students during the school by the exercise of good engineering practice , has been an important goal of the process control laboratory construction . Combination of automation professional and Control Technology and Instrument professional teaching characteristics and laboratory construction projects , to tank level experimental apparatus for the controlled object , the development of LabVIEW - based remote control teaching experiment system is a main research content . Tank level mathematical model of the experimental device , and model parameters obtained by the method of least squares parameter identification ; -depth analysis of the basic structure of the traditional fuzzy controller , developed a dynamic query statement fuzzy controller to overcome the traditional fuzzy control static error the disadvantage ; combined with the advantages of traditional fuzzy control and conventional PID , the development of self-tuning fuzzy PID and fuzzy - PID composite fuzzy controller , use LabVIEW / simulation tool developed controller simulation . With the improved algorithm , to facilitate students to master the working principle of PID parameters control the performance impact , and shorten the setting time of the PID parameters . Several methods based on LabVIEW remote control , focuses on the use the LabVIEW Web server and AppletVIEW of tools package to achieve the water tank level system remote control and two remote control methods were compared . NI cFP - 2120 controller to form a virtual instrument remote distributed control system , students can select remote control mode according to specific needs , improve the flexibility and openness of the experimental system . Based on LabVIEW virtual instrument remote control system includes not only a simulation , automatic control principle experiment, the parameter identification experiment , but also to provide students with a variety of advanced control algorithms research experiments . Experimental teaching, students can take to get production process control system design debugging and parameter identification training . Same time, the experimental teaching system , but also to improve the situation of insufficient laboratory hardware resources , to improve the utilization of laboratory resources .
