Safety, privacy and comfort are elements that need to be improved on Swedish shelters. Since several homeless individuals often share bedrooms, it is not uncommon for them to be exposed to violence, harassment and theft or a generally disturbing environment during their stay. These are all contributing factors to an increased difficulty in getting out of homelessness. Enfold is a flexible w

Den här uppsatsen ämnar att undersöka varför Sverige skickade in en Natoansökan efter Rysslands invasion av Ukraina under 2022 istället för efter annekteringen av Krimhalvön 2014. Sverige har en lång historia av militär alliansfrihet och den svenska säkerhetspolitiken har präglats av Hultqvist doktrinen sedan 2014. Varför övergavs den 2022? Genom en kritisk diskursanalys kombinerat med säkerhetise

Our problem considered was whether a virtual environment could be used for development of visual servoing control algorithms.

We have used a virtual environment for the comparison of several kinds of controllers. The virtual environment is done in Java, and it consists of two industrial robots, IRB 2000 and IRB 6, a camera stereo system with two cameras mounted on the end-effector of the IRB 6,

In process industry many control loops are far from optimally tuned. In this master's thesis a tool for rapid process identification and control design has been developed. The tool, which is implemented in Matlab 5.3, identifies a process model out of the step response of the real process. A PI or PID controller can then be designed and evaluated. The tool contains three different automatic de

One problem when new controllers or control systems are built is the test of the controllers or the control systems. One way to test the controller is to build a real process to test the controller against. Another way to test the controller is to build the process-model in some kind of computer simulation tool. The advantages of using a simulation tool in a computer are quite many. For example

Industrial robots are used/configured/programmed by several different types of users/programmers. The control system should preferably expose a uniform view for each programming situation. Such views were defined by the Open Robot Control (ORC) architecture, developed within the department in an earlier project. This project refines and evaluates some robot programming principles. First, earlier p

An adaptive tracking controller is implemented using an industrial robot, the ASEA IRB L6/2. A dynamical model is used to simulate the robot together with the control law. The control law is implemented using two IBM AT compatible computers, and comparison with a PD controller is done.

The thesis is made within the Department of Automatic Control in Lund. A program "VISIDYN" is written in C for Sun 3/50. The program is to be used in education, but it can also, with a few extensions, be used as a tool by more experienced designers. VISIDYN is a graphics based system for exploring linear dynamic systems. The basic idea is that a linear dynamic system can be examined from
