1. On low order controller synthesis using rational constraints
Sammanfattning : In order to design robust controllers, H-infinity synthesis is a common tool to use. The controllers that result from these algorithms are typically of very high order, which complicates implementation. LÄS MER
2. Causal MMSE Filters for Personal Audio : A Polynomial Matrix Approach
Sammanfattning : This thesis is devoted to the study of synthesis of causal filters for generating personal sound zones. Personal sound zones, personal audio or personal sound is the theory and practice of steering sound in such a way that it is amplified in one region and suppressed in another. LÄS MER
3. Short Term Scheduling of Hydrothermal Power Systems With Integer Hydro Constraints
Sammanfattning : The thesis presents models for short term planning (24 hours) of a hyro dominated hydrothermal power system. The purpose of the models is to minimizae the system operation costs to provide a forecasted load and keep enough spinning reserve... LÄS MER
4. Constructive Methods for Inequality Constraints in Control
Sammanfattning : In practical control problems there are always constraints on inputs and system variables. The constraints are often described by inequalities and there is a need for methods that take them into account. This thesis consists of three parts. LÄS MER
5. Linear control of systems with actuator constraints
Sammanfattning : This thesis deals with the problem of how to design a linear and time invariant controller (continuous- or discrete-time) for a SISO- or SIMO-system with amplitude constraints in the actuator. One of the basic ideas is to model the constraints by means of a 'disturbance' δ acting at the input of the process. LÄS MER
