Abstract
A remote state estimation method based on a polling protocol belongs to the field of information-physical systems. The present invention solves the problem of slow estimation speed and large estimation error of existing remote state estimation methods. The method of the present invention is specifically as follows: Step 1, establish an information-physical system model; Step 2, determine whether the established information-physical system model is a linear system; if the established information-physical system model is a linear system, then directly execute step 3; otherwise, if the established information-physical system model is a nonlinear system, then the established information-physical system model is linearly processed to obtain a linear information-physical system model, and then execute step 3; Step 3, design a remote state estimator, and perform remote state estimation on the information-physical system model based on the designed remote state estimator; Step 4, transmit the remote state estimation result of step 3 to the controller, and the controller makes a decision. The method of the present invention can be applied to remote state estimation in information-physical systems.
