Study on fuzzy-logic PID control system of synchronous jack-up system of turbine runner static equilibrium experiment

Basing on the LabVIEW platform, a fuzzy-logic PID controller is developed. And the controller is applied to the control system of synchronous jack-up system of turbine runner static equilibrium experiment. With a unit step signal input, the control system was simulated. The result shows that, with only a small amount of overshoot, the control system using fuzzy-logic PID controller responses and stabilizes faster than the one using normal PID controller. Fuzzy-logic PID controller shows great value in the practical implementation of the hydraulic system control. It also can be extended to other areas such as bridge reinforcing and migration of cultural relic and so on.
