  1. 1. Linear Parameter-Varying Systems - an approach to gain scheduling

    Författare :Fredrik Bruzelius; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear parameter-varying systems; linear matrix inequalities; h-inf control; gain scheduling; nonlinear L2 l2 control;

    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

  3. 2. On Parameter Estimation and Control of Time-Varying Stochastic Systems

    Författare :Bengt Lindoff; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Adaptive Predictive Control; Adaptive Stochastic Control; Dual Control; Convergence Analysis; Quadratic Forms; Forgetting Factor; Recursive Least Squares; Recursive Estimation; Linear Systems; Time-Varying Stochastic Systems; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor.

  4. 3. Control of Constrained Dynamical Systems with Performance Guarantees: With Application to Vehicle motion Control

    Författare :Ankit Gupta; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear matrix inequalities; Robust control; Invariant set; Semi-definite program; Linear parameter varying system; Linear fractional transformation;

    Sammanfattning : In control engineering, models of the system are commonly used for controller design. A standard control design problem consists of steering the given system output (or states) towards a predefined reference. Such a problem can be solved by employing feedback control strategies.

  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. Modeling, analysis, state and parameter estimation of faulty induction machines

    Författare :Mikael Stocks; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : This thesis covers a broad range of subjects pertaining to induction machines, faulty as well as healthy ones. Firstly, a completely new and unconventional methodology for deriving simplest possible, yet sufficiently accurate, mathematical models for induction machines with general electrical faults is presented.
