On the college students experimental course, because the single tank water level control the complexity of this system and the real-time requirements of the high, the system control strategy based on different experimental content, need comprehensive grasp of automatic control theory and related knowledge. This article through to the single tank water level control system and Study on the current status of the Kingview software, select MCGS6.2 and PID control strategy on the experimental system for real-time control, establishes the mathematical model of single water tank. Introduces the basic principle of PID control and PID algorithm, and according to the algorithm comparison and selection of the incremental PID algorithm, based on Kingview MCGS6.2 script language PID level control simulation interface and the algorithm program, system simulation, and by adjusting the parameter of PID. The experimental system structure research, established a single water tank experiment system is a mathematical model, and the system parameters identification, authentication in MCGS6.2 Kingview control system has good control
