1. Input-Output Stability Analysis of Networked Control Systems
Sammanfattning : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). LÄS MER
2. Complexity Issues, Validation and Input Design for Control in System Identification
Sammanfattning : System identification is about constructing and validating modelsfrom measured data. When designing system identificationexperiments in control applications, there are many aspects toconsider. One important aspect is the choice of model structure.Another crucial issue is the design of input signals. LÄS MER
3. Ammonium based aeration control in wastewater treatment plants : Modelling and controller design
Sammanfattning : Wastewater treatment involves many processes and methods which make a treatment plant a large-scaled and complex system. A fundamental challenge is how to maintain a high process efficiency while keeping the operational costs low. LÄS MER
4. Linear Parameter-Varying Systems - an approach to gain scheduling
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
5. Pontryagin approximations for optimal design
Sammanfattning : This thesis concerns the approximation of optimally controlled partial differential equations for applications in optimal design and reconstruction. Such optimal control problems are often ill-posed and need to be regularized to obtain good approximations. LÄS MER
