?Abstract: The Predictive Functional Control(PFC)technology is introduced,a multivariable predictive functional control algorithm based on feed-forward compensation decoupling technique is applied to three-tank water-level control system. The simulation results of PFC in three-tank water-level control system show that the PFC control law have the following properties: simple calculation, strong robustness, strong disturbance attenuation and high control precision.
