1. 1. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors

   University essay from KTH/Mekatronik och inbyggda styrsystem

   Author : Arvid Bergvall; Pontus Lundman; [2023]
   Keywords : Mechatronics; Gantry; Stepper motor; Control; Linear Quadratic Regulator; Adaptive LQI; PID; Mekatronik; Gantry; Stegmotor; Reglerteknik; LQR; Adaptiv LQI; PID;

   Abstract : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. READ MORE

3. 2. Predictive control of fuel cell hybrid construction machines

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Aniroodh Kumaraswamy; [2023]
   Keywords : Fuel cell; Construction Vehicle; Energy management; Optimization; Model Predictive Control; Load prediction; Bränslecell; Byggmaskiner; Energihanteringssystem; Optimeringsproblem; Modellprediktiv Reglering; Belastnings-estimering;

   Abstract : Sedan industriella revolutionen har hastigheten av global uppvärmning och föroreningar i miljön ökat betydligt. Företag i fordonsindustrin arbetar aktivt för att göra sina produkter mer hållbara genom att bland annat minska utsläppen, minimera användningen av icke-förnybara resurser samt att återvinna.

4. 3. Optimal Control of An Energy Storage System Providing Fast Charging and Ancillary Services

   University essay from KTH/Optimeringslära och systemteori

   Author : Max Völcker; Hugo Rolff; [2023]
   Keywords : Optimal Control; Model Predictive Control; Dynamic Programming; State-Space Representation; Monte Carlo Simulation; Frequency Regulation; Fast Charging; Energy Storage Systems; Net Present Value; Optimal styrteori; Modell-prediktiv reglering; Dynamisk programmering; Frekvensreglering; Snabbladdning; Energilager; Nuvärde;

   Abstract : In this thesis, we explore the potential of financing a fast charging system with energy storage by delivering ancillary services from the energy storage in an optimal way. Specifically, a system delivering frequency regulation services FCR-D Up and FCR-D Down in combination with energy arbitrage trading is considered. READ MORE

5. 4. Control of an Over-Actuated Vehicle for Autonomous Driving and Energy Optimization : Development of a cascade controller to solve the control allocation problem in real-time on an autonomous driving vehicle

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Gianmarco Grandi; [2023]
   Keywords : LTV-MPC Linear Time-Varying Model Predictive Controller ; Trajectory following; Energy consumption; Vehicle stability; Vehicle model; Real-time performance; LTV-MPC Controllo a predizione del modello lineare tempo variabile ; Inseguimento di traiettoria; Consumo energetico; Stabilità del veicolo; Modello del veicolo; Prestazioni in tempo reale; LTV-MPC Linjär tidsvariabel modellförutsägande styrning ; spårföljning; energiförbrukning; fordonsstabilitet; fordonsmodell; prestanda i realtid;

   Abstract : An Over-Actuated (OA) vehicle is a system that presents more control variables than degrees of freedom. Therefore, more than one configuration of the control input can drive the system to a desired state in the state space, and this redundancy can be exploited to fulfill other tasks or solve further problems.

6. 5. Optimal Path Planning for Aerial Swarm in Area Exploration

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Johanna Norén; [2022]
   Keywords : Optimization; Path planning; Dynamic programming; Area exploration; Aerial swarm; Multi-agent system; Optimering; Ruttplanering; Dynamisk programmering; Områdesutforskning; Drönarsvärm; Fler-agentsfall;

   Abstract : This thesis presents an approach to solve an optimal path planning problem for a swarm of drones. We optimize and improve information retrieval in area exploration within applications such a ‘Search and Rescue’-missions or reconnaissance missions. For this, dynamic programming has been used as a solving approach for a optimization problem. READ MORE
