Asynchronous H ∞ Estimation for Two-Dimensional Nonhomogeneous Markovian Jump Systems with Randomly Occurring Nonlocal Sensor Nonlinearities

Abstract EN

This paper is devoted to the problem of asynchronous H ∞ estimation for a class of two-dimensional (2D) nonhomogeneous Markovian jump systems with nonlocal sensor nonlinearity, where the nonlocal measurement nonlinearity is governed by a stochastic variable satisfying the Bernoulli distribution.

The asynchronous estimation means that the switching of candidate filters may have a lag to the switching of system modes, and the varying character of transition probabilities is considered to reside in a convex polytope.

The jumping process of the error system is modeled as a two-component Markov chain with extended varying transition probabilities.

A stochastic parameter-dependent approach is provided for the design of H ∞ filter such that, for randomly occurring nonlocal sensor nonlinearity, the corresponding error system is mean-square asymptotically stable and has a prescribed H ∞ performance index.

Finally, a numerical example is used to illustrate the effectiveness of the developed estimation method.
