Abstract:This technical paper studies robust H (a) filtering design for 2-dimensional (2-D) systems and the focus is on finding other methods to further reduce the conservativeness when the 'polynomially dependent on the parameter' technique 2000 fails to do so. First, the possible sources of conservativeness of the existing results are explored, and then two algorithms are proposed. Since no special structures are required in the introduced variables, the algorithms can further reduce the conservativeness. In addition, the initial conditions of the algorithms are discussed and an example is provided to demonstrate the effectiveness of the conclusions.
