Abstract: In order to accomplish the wind speed control system for DFD wind tunnel in certain university, a set of computerized wind control
system is designed based on LabVIEW. Both hardware and software of the system are designed. On the basis of introduction of general PID control
strategy, the control accuracy of wind speed and PID parameters tuning are studied. The tuning procedures for PID parameters are improved,
and the strategy of wind speed closed loop quantization PID is stated. The control software is implemented through LabVIEW codes.
The reliability and practicability of quantization PID method have been proved through practical verification. The system is superior and practical.
