H-infinity filtering for two-dimensional systems with mixed time delays, randomly occurring saturations and nonlinearities Academic Article uri icon


  • 2014 Taylor & Francis. This paper is concerned with the script H filtering problem for the two-dimensional (2-D) systems with mixed time delays which comprise both the discrete time-varying delays and the discrete distributed delays in states. Randomly occurring nonlinearities (RONs) and randomly occurring saturations (ROSs) are also considered, respectively, in the state-space model and the measurement output equation to reflect the nonlinear disturbance appearing in a random way and the limited communication capabilities of the sensors. The aim of this paper is focused on the design of a full-order script H filter such that the script H performance is guaranteed in the simultaneous presence of the mixed tim delays, RONs and ROSs. By utilizing the Kronecker product and the inequality technique, an energy-like function is developed to establish some sufficient criteria under which the filtering error system satisfies the prescribed script H disturbance attenuation performance. Furthermore, explicit expression of the filter parameters is also characterized. Numerical example provided in the end of the paper further demonstrates the effectiveness of the proposed design scheme.
