1. 1. State estimation of nonlinear systems

   Författare :Saleh Sayyaddelshad; Alexander Medvedev; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : Observer design for nonlinear systems is a popular problem in control theory that has beenstudied from many angles. Since the system state variables, in general, are not available, stateestimation is essential in many control applications, which is why the problem is so attractivefor researchers. LÄS MER

3. 2. Task-oriented control and coordination of multi-agent systems under varying constraints

   Författare :Pian Yu; Dimos V. Dimarogonas; Carlo Fischione; Christos Cassandras; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent systems; uncertain systems; temporal logics; event-triggered control; control synthesis; conflict resolution; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Multi-agent systems (MAS) offer a tremendous potential to improve the quality of modern society life. For instance, robot networks have been widely used for providing services such as search and rescue missions, surveillance and data collection, healthcare and entertainment. LÄS MER

4. 3. Identification and Estimation for Models Described by Differential-Algebraic Equations

   Författare :Markus Gerdin; Torkel Glad; Lennart Ljung; Manfred Deistler; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Differential-Algebraic Equations; Identifiability; Nonlinear systems; Modelling; Identification; Descriptor systems; Automatic control; Reglerteknik;

   Sammanfattning : Differential-algebraic equations (DAEs) form the natural way in which models of physical systems are delivered from an object-oriented modeling tool like Modelica. Differential-algebraic equations are also known as descriptor systems, singular systems, and implicit systems. LÄS MER

5. 4. Funnel-Based Control for Coupled Spatiotemporal Specifications

   Författare :Farhad Mehdifar; Dimos V. Dimarogonas; Charalampos P. Bechlioulis; Bayu Jayawardhana; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funnel-Based Control; Prescribed Performance Control; Uncertain Nonlinear Systems; Time-Varying Output Constraints; Coupled Spatiotemporal Constraints; Formation Control; Multi-Agent Systems; Trattbaserad kontroll; föreskriven prestandakontroll; osäkra icke-linjära system; tidsvarierande utgångsbegränsningar; kopplade rumsliga begränsningar; formationskontroll; multiagentsystem; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. LÄS MER

7. 5. Nonlinear Model-based Control of Automotive Powertrains

   Författare :Jonas Fredriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stability; diesel engine control; nonlinear control; gearshifting; air-to-fuel ratio control; drive- line oscillations; backstepping; powertrain modeling; powertrain control;

   Sammanfattning : In recent years the focus of powertrain control has shifted perspective from control of the individual powertrain components to control of the complete powertrain, so-called integrated powertrain control. The idea presented in this thesis is to view the powertrain as one single control object and to used the engine as a torque actuator to the rest of the driveline. LÄS MER
