   Sammanfattning : In recent years the interest for gain scheduling methods has increased. Gain scheduling is a collection of methods that try to tackle the challenging problem of nonlinear control in a divide and conquer manner. The use of local linear system theory to obtain a non-local controller is the fundament of the gain scheduling methods. LÄS MER

4. 3. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space

   Författare :Edoardo De Robertis; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomografi; medicinsk instrumentering; radiologi; Klinisk fysiologi; tomography; medical instrumentation; Respiratory system; Andningsorganen;

   Sammanfattning : Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. LÄS MER

5. 4. A Nonlinear Optimization Approach to H2-Optimal Modeling and Control

   Författare :Daniel Petersson; Johan Löfberg; Lennart Ljung; Roland Toth; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model reduction; LPV system; linear parameter varying; controller; control synthesis; H2; H2-norm; nonlinear optimization;

   Sammanfattning : Mathematical models of physical systems are pervasive in engineering. These models can be used to analyze properties of the system, to simulate the system, or synthesize controllers. However, many of these models are too complex or too large for standard analysis and synthesis methods to be applicable. LÄS MER

7. 5. Gain-Scheduled Controller Design

   Författare :Adrian Ilka; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Guaranteed cost control; Gain-scheduled control; Bellman-Lyapunov function; Lyapunov theory of stability; Robust control; Input output constraints; LPV system;

   Sammanfattning : This thesis is devoted to controller synthesis, i.e. to finding a systematic procedure to determine the optimal (sub-optimal) controller parameters which guarantees the closed-loop stability and guaranteed cost for uncertain nonlinear systems with considering input/output constraints, all this without on-line optimization.
