Parameter-dependent mixed H2/H∞ filtering for linear parameter-varying systems

In this study, the authors deal with the mixed H₂/H_∞ filtering problem for continuous-time systems. The system model is subject to parameter variation and the parameters of the model vary slowly in the polytope. The parameters of the designed filter are dependent on variation, which is measured online. A new design approach is proposed by increasing the flexible dimensions in the solution space. An illustrative example shows the new features of the proposed design approach.
