  1. 11. Resonance Mitigation in the Attitude Control of a Flexible Large Solar Sail

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Jonas Linnros; [2023]
    Keywords : Resonance; Control theory; Mechanics; Solar sail; PID; Space; Resonans; Reglerteknik; Mekanik; Solsegel; PID; Rymd;

    Abstract : This project is about the design process of a resonancemitigating algorithm for a large solar sail. The solar sail isa structure made up by four long booms in a cross patternwith suspended sails between the edges of the booms. Thespacecraft in this report is controlled using smaller rotatingsails at each tip of the booms. READ MORE

  6. 15. Validation of the attitude control of KNATTE with flexible appendages

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Christoffer Johansson; [2022]
    Keywords : KNATTE; flexible appendages; control; SMC; LQG; PWM; PWPF;

    Abstract : The effect of flexible panels on a spacecraft during attitude movement may induce problems if not correctly accounted for in the control system for the spacecraft. The aim of this thesis is to find and evaluate, control algorithms that could be suitable for the Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) with two flexible mock-up solar panels during an attitude movement of 20 degrees.
