2. 1. Robust Verification and Identification of Piecewise Affine Systems

   Author : Jakob Roll; Lennart Ljung; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise affine systems; Verification; Robustness; Identification; Mixed-integer programming;

   Abstract : iecewise affine systems constitute an important subclass of hybrid systems, and consist of several affine dynamic subsystems, between which switchings occur at different occasions. As for hybrid systems in general, there has been a growing interest for piecewise affine systems in recent years, and they occur in many application areas. READ MORE

4. 2. Local and Piecewise Affine Approaches to System Identification

   Author : Jakob Roll; Lennart Ljung; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Identification of nonlinear systems is a multifaceted research area, with many diverse approaches and methods. This thesis considers two different approaches: (nonparametric) local modelling, and identification of piecewise affine systems. READ MORE

5. 3. Active Vibration Control of Multibody Systems : Application to Automotive Design

   Author : Claes Olsson; Alexander Medvedev; Stephen Elliott; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Vibration Isolation; Feedback Control; Adaptive Filtering; Saturation; Limit Cycles; Multi Body Systems; Modelling; Simulation; Non-linearity; Gain Scheduling; Structure Flexibility; Automatic control; Reglerteknik;

   Abstract : Active vibration control to reduce vibrations and structure borne noise is considered using a powerful multi-disciplinary virtual design environment which enables control system design to be considered as an integral part of the overall vehicle design. The main application studied is active automotive engine vibration isolation where, first, the potential of large frequency band multi-input multi-output H2 feedback control is considered. READ MORE

6. 4. Applied estimation of piecewise constant parameters

   Author : Soheil Salehpour; Alexander Medvedev; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Abstract : A time-varying linear system is a realistic description of many industrial processes, and nonlinear behavior can then also be accounted for. Then, we can consider a linear system with time-varying parameters as the model uncertainty, \emph{e.g.} an AR(X) model or an affine input-output approximation. READ MORE

7. 5. On Verification of Switched Systems using Abstractions

   Author : Valur Einarsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis deals with modeling and analysis of a special class of hybrid systems, i.e., systems displaying behavior of both continuous and discrete nature. READ MORE
