21. Regressor Selection in System Identification using ANOVA
Abstract : The aim of this work is to nd a good method to select regressors for nonlinear system identification. A literature survey over possible methods to select the model structure for nonlinear systems, mainly autoregressive processes, is first given. The main ideas are:1. Compare estimated models, using different regressor vectors, with each other. READ MORE

22. On Automation of the PID Tuning Procedure
Abstract : Within process industry, and in many other areas, the PID controller is responsible for handling regulatory control. An educated guess is that the number of executing PID control loops lies in the billions (2011) and there are no signs indicating a decrease of this number. Properly tuning the PID controller, i.e. READ MORE

23. On Multivariable and Nonlinear Identification of Industrial Robots
Abstract : The main objective of the thesis is the identification of flexibilities and nonlinearities in mathematical models of industrial robots. In particular, a nonparametric frequency-domain estimation method for the multivariable frequency response function (MFRF) has been evaluated and analyzed for the robot application. READ MORE

24. Structural Control and Identification of Civil Engineering Structures
Abstract : In general, the main purpose of a structural control system is to apply powerful control techniques that improve the behaviour of civil structures under various kinds of dynamic loading. The first part of this thesis presents novel applications of posicast and input shaping control schemes that have never previously been applied in the field of structural control. READ MORE

25. On input design in system identification for control
Abstract : There are many aspects to consider when designing system identification experiments in control applications. Input design is one important issue. This thesis considers input design both for identification of linear time-invariant models and for stability validation. READ MORE
