Robust Filtering for Networked Stochastic Systems Subject to Sensor Nonlinearity

Abstract EN

The problem of network-based robust filtering for stochastic systems with sensor nonlinearity is investigated in this paper.

In the network environment, the effects of the sensor saturation, output quantization, and network-induced delay are taken into simultaneous consideration, and the output measurements received in the filter side are incomplete.

The random delays are modeled as a linear function of the stochastic variable described by a Bernoulli random binary distribution.

The derived criteria for performance analysis of the filtering-error system and filter design are proposed which can be solved by using convex optimization method.

Numerical examples show the effectiveness of the design method.
