Nanosatellite rendezvous with electrical propulsion Nanosatellites -- Control systems Orbital rendezvous (Space flight) Propulsion systems Cubesatellites UCTD Thesis (MEng)--Stellenbosch University, 2024. ENGLISH ABSTRACT: Nanosatellites are low-cost and effective solutions to various scenarios. Being able to rendezvous would promote their uses even more. However, due to size constraints, limited available thrust from conventional thrusters, and increased susceptibility to external effects, determining a rendezvous trajectory becomes a significant challenge. Existing rendezvous methods utilise impulse manoeuvres, such as Hohmann transfers or phasing, that cannot be performed by nanosatellites with low-thrust propulsion due to prolonged burn times. This research presents two controllers that combine Model Predictive Control (MPC) with Keplerian- and Clohessy-Wiltshire orbital equations to robustly determine optimal rendezvous trajectories for low-thrust nanosatellites. Through rigorous testing within commercially available orbital simulation software, namely Dawn Dusk Satellite Simulator (D2S2), we show that both controllers can determine optimal rendezvous trajectories at a high success rate for various initial conditions while mitigating external effects. AFRIKAANSE OPSOMMING: Nanosatelliete, wat bekend is vir hul koste-doeltreffendheid en veelsydigheid, bied aansienlike potensiaal vir ’n verskeidenheid van toepassings. Die vermo¨e om satelliet saamkoms te bewerkstellig sou hul nut verder verbeter. Tog, as gevolg van groottebeperkings, beperkte stuwingsvermo¨e van konvensionele stuwers, en ’n verhoogde kwesbaarheid vir eksterne versteurings, word die bepaling van saamkomstrajekte ’n gedugte uitdaging. Tradisionele saamkomstrategie¨e wat steun op impuls baseerde metodes soos Hohmann-oordragte of “phasing” is onprakties vir nanosatelliete met lae stuwing as gevolg van verlengde brandtye. Hierdie navorsing stel twee beheerders voor wat Modelvoorspellingsbeheer (“MPC”) met Kepleriaanse en Clohessy-Wiltshire baanvergelykings integreer, en sodoende die robuuste bepaling van optimale saamkomstrajekte vir nanosatelliete met lae stuwing moontlik maak. Deeglike assessering binne ’n kommersieel beskikbare orbitale simulasieprogram, “Dawn Dusk Satellite Simulator” (D2S2), toon die ho¨e sukseskoers van beide beheerders vir ’n verskeidenheid van aanvangstoestande asook hul vermo¨e om eksterne invloede effektief te beperk.
