  2. 16. Subspace Selection Techniques for Classification Problems

    Author : David Lindgren; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear subspaces for regression; Asymetric classification; Subspace parameterization; Clustered regression analysis;

    Abstract : The main topic of this thesis is linear subspaces for regression - how to find the subspaces and how to evaluate them. The motivation to do regression in a subspace is numerical as well as computational - numerical in the sense that the subspace can filter out the relevant components or features of the problem, computationally in the sense that this filtering can be done quickly and then can nonlinear predictionby artificial neural networks, for instance, be conducted in lower dimensionality.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse problem; ill-conditioning; upper block triangular Toeplitz matrix; regularization; wavelet parameterization; least squares problem; input estimation; time domain; linear and nonlinear systems; load identification;

    Abstract : The automotive industry faces an increasing demand for virtual prototyping to simulate the operation conditions of vehicles and subsystems. Each component, as well as the complete vehicle, must meet the desired design requirements in a time- and cost-efficient development process. READ MORE

  6. 19. Geometry-based Radio Channel Characterization and Modeling: Parameterization, Implementation and Validation

    Author : Meifang Zhu; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The propagation channel determines the fundamental basis of wireless communications, as well as the actual performance of practical systems. Therefore, having good channel models is a prerequisite for developing the next generation wireless systems. This thesis first investigates one of the main channel model building blocks, namely clusters. READ MORE

  7. 20. Analytic Parameterization of Stabilizing Controllers for the Moore-Greitzer Compressor Model

    Author : Alina Andersson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear control; Moore-Greitzer compressor model; Dynamic output feedback; Compressors; Nonlinear control systems; Stability robustness; Constraints; Nonlinearity; Lyapunov stability;

    Abstract : This work presents an extension, simplification and application of a design procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints (QC). Our method was motivated by the challenges of output feedback control design for the three-state Moore-Greitzer (MG) compressor model. READ MORE
