Advanced Spacecraft Power Subsystem Design -- 2

We are designing a spacecraft power subsystem using MATLAB/Simulink with focus on a three-port converter topology (TAB) for solar, battery, and load interfacing and The final control system will be implemented in LabVIEW and deployed on NI myRIO hardware.


I'm working on a multi-stage project involving advanced control of isolated multiport DC-DC converters using Simulink.



I’m looking to begin Triple Active Bridge (TAB) converter using fixed phase-shift control, and with optimization and load scheduling.


Project Roadmap Overview:

We have ready Triple Active Bridge (TAB)
Simulink model


Fixed phase-shift control implementation



Validate bidirectional power transfer (e.g., from a source to a load)



Stage 1: Triple Active Bridge (TAB)
Extend to 3-port system (solar input, battery, load)



Apply individual phase-shift control for each port pair



Simulate different operating scenarios (e.g., power-limited, eclipse mode)



Stage 2: Adaptive Optimization
Introduce a metaheuristic algorithm (e.g., multiverse optimization) for MPPT



Optimize phase-shift angles dynamically based on efficiency and space scenario
