Research of PFC algorithm based on grey system model in networked control system

The Networked Control System with stochastic time delays and data drop can be regarded as the grey system which involves stochastic interferences and stochastic variables.The generalized controlled object is modeled as a grey system model and it is proposed in the passage an algorithm of predictive functional control based on grey system model. The formula of how to calculate the output of predictive model and the equation of control law is deduced; A NCS simulation platform is built with event-clock-driven controller nodes and clock-driven sensor nodes and actuator nodes. The simulation results show that the algorithm has a better anti-interference ability and quicker dynamic response and it is easy to be calculated online with good control capability.
