Abstract: Large storage capacity and large lag are the characteristies of large-scale hydraulic models.To improve the static and dynamic indices of the control system largely the dual-loop control of fluxand and water level is applied in the actual design and different optimization algorithms are adopted according to different characterisitics of water level control and flux control,that will insure the quality of the large-scale hydraulic model experiments

Key words: large-scale hydraulic models, PID algorithm, algorithm optimization
