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

    Författare :Alina Andersson; Institutionen för reglerteknik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Modelling and Numerical Analysis of the Centrifugal Compressor and its Operation in the Pressurised SOFC GT Process

    Författare :Andre Hildebrandt; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; radial compressor; Gas Turbine; Termisk teknik; Solid Oxide Fuel Cell; termodynamik;

    Sammanfattning : Small-scale power plants based on the SOFC-GT (Solid Oxide Fuel Cell-Gas Turbine) system are foreseen for future application such as APU units in flight transportation systems or stationary power production. Although these new systems offer high load flexibility and potentially high efficiency, there are several constraints referring to thermal/mechanical stress of the fuel cell as well as to a potential risk of aerodynamic instability of the GT compressor due to the different physical behavior of the SOFC and the GT.

  4. 3. Modeling and control of actuators and co-surge in turbocharged engines

    Författare :Andreas Thomasson; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The torque response of the engine is important for the driving experience of a vehicle. In spark ignited engines, torque is proportional to the air flow into the cylinders. Controlling torque therefore implies controlling air flow. LÄS MER
