Dear all, we are pleased to announce that IQClab, next to continuous-time robustness analysis, now fully supports performing robustness analyses for discrete-time uncertain systems. This was already possible for most uncertainty classes with the exception of the class of diagonally repeated sector-bounded and slope restricted nonlinearities. Therefore, we have now implemented a discrete-time (asymptotically) tight parameterization of the full-block Zames-Falb multiplier as reported in [23]. A new release of IQClab is now available.
Update: IQClab now facilitates your regional analysis
Dear visitor, supporter, and/or user of IQClab. This is to let you know that IQClab is now capable of performing various types of invariant/regional analyses. Please follow this link for further details. A new release of IQClab is now available.
IQClab is now live

This portal gives you access to state of the art integral quadratic constraint (IQC) based tools for performing robustness analyses and designing control algorithms for a large class of uncertain and linear parameter varying (LPV) systems. In addition, IQClab consists of an extensive set of auxiliary tools and functions for performing model reduction, implementing control switching schemes, generating performance weighting functions, among others. Not only are the tools easy to use, but they also have a modular build and can be applied in combination with different parsers and solvers. This allows developers to seamlessly include new linear matrix inequality (LMI) and IQC based algorithms as well as other extensions.
