  1. 1. Evaluation of Model-Based Design Using Rapid Control Prototyping on Forklifts

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Author : Lovisa Jansson; Amanda Nilsson; [2019]
    Keywords : Rapid Control Prototyping; Model-Based Design; Forklift; Automatic control; Speedgoat; Model Predictive Control; MPC; P Controller; Models; Simulink; Matlab; Minimum Jerk Trajectory;

    Abstract : The purpose of this thesis is to evaluate Rapid Control Prototyping which is apart of the Model-Based Design concept that makes it possible to convenientlytest prototype control algorithms directly on the real system. The evaluation ishere done by designing two different controllers, a gain-scheduled P controllerand a linear Model Predictive Controller (mpc), for the lowering of the forks of aforklift. READ MORE

  2. 2. FE based method for simulation of rock-loading on a truck

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Tamim Kohestani; Ali Zeaiter; [2019]
    Keywords : FEM; Rock loading; Nastran; LS-DYNA; ANSA; META; Contact; Linear; non-linear; Explicit; Implicit.;

    Abstract : Volvos trucks are used to carry boulders of varying sizes from different mining sites or construction sites. These boulders are loaded onto the dumper of the truck by a wheel-loader which drops the boulders from various heights causing an impulse like force which distributes throughout the frame and to the rest of the truck.

    Keywords : rtls;

    Abstract : Fältet inomhuspositionering är en viktig och stor front och är i fortsatt och snabb utveckling inom IoT-teknik och digitalisering av storstäder. Detta arbete är utformat för att hitta och bygga en lämplig teknik för att komprimera olinjäriteter från multipatutbredning. READ MORE

  4. 4. Direct Lift Control of Fighter Aircraft

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Author : Philip Öhrn; Markus Åstrand; [2019]
    Keywords : direct lift; direct lift control; fighter aircraft; model predictive control; linear quadratic control; MPC; LQ; flight path angle;

    Abstract : Direct lift control for aircraft has been around in the aeronautical industry for decades but is mainly used in commercial aircraft with dedicated direct lift control surfaces. The focus of this thesis is to investigate if direct lift control is feasible for a fighter aircraft, similar to Saab JAS 39 Gripen, without dedicated control surfaces. READ MORE

  5. 5. An Analysis of Financial Stress in the Chinese Economy: A TVAR Approach

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Oskar Landgren; Jack Crooks; [2018]
    Keywords : Financial Stress; TVAR; Nonlinearities; China; Business and Economics;

    Abstract : In this paper, we look to develop understanding of the nature and potential impact of financial stress and fiscal shocks in the Chinese economy, examining how such stress spreads through the economy and how monetary policy can exaggerate or mitigate the resultant effects. In order to do so, we construct a TVAR model on Chinese quarterly data. READ MORE
