Estimating the States of Nonlinear Systems under Communication Constraints
A state estimation problem of a class of nonlinear oscillatory systems under information constraints imposed by limited capacity of the communication channel is analyzed. A binary time-varying coder-decoder scheme is described and the results of a theoretical analysis of state estimation of nonlinear systems, represented in Lurie form based on the Passification Theorem, are presented, showing that the estimation error exponentially tends to zero for a sufficiently high transmission rate. The experimental results for multi-pendulum mechatronic setup are presented, showing the efficiency of the proposed method.
