Design method and system for anti-outlier proportional-integral observer of networked two-dimensional system

The invention discloses a networked two-dimensional system anti-outlier proportional-integral observer design method and system, and the method comprises the steps: building a networked two-dimensional discrete system state space model, and carrying out the preliminary modeling of a state vector of a system, process noise in the system, and a nonlinear term; constructing redundant channel measurement output with a bidirectional evolution characteristic; designing an anti-outlier proportional-integral observer structure with an adaptive saturation function, and giving out gain matrix parameters of the designed observer; defining an estimation value and an estimation error of a state vector of the system, defining an augmentation vector, and converting the networked two-dimensional discrete system into an augmentation dynamic estimation error system; system performance evaluation indexes are introduced, observer gain matrix parameters are substituted into the augmented dynamic estimation error system, and if pe
