A system for maintaining attitude control under degraded or depleted energy source conditions using multiple electric propulsors, the system comprising: a plurality of propulsors (104 a-n); at least an energy source providing electric power to the plurality of propulsors (104 a-n); and a vehicle controller communicatively coupled to each propulsor of the plurality of propulsors (104 a-n), the vehicle controller designed and configured to: calculate initial power levels for the plurality of propulsors (104 a-n), the initial power levels including an initial power level for each propulsor of the plurality of propulsors (104 a-n); detect a present power output capability of the at least an energy source; calculate at least a power demand of the plurality of propulsors (104 a-n) as a function of the initial power levels; determine that the present power output capability is insufficient to match the at least a power demand of the plurality of propulsors (104 a-n); and for each initial power level of the plurality of initial power levels: generate a reduced power level, the reduced power level being less than the initial power level; and direct a corresponding propulsor of the plurality of propulsors (104 a-n) to consume electrical power at the reduced power level. a plurality of propulsors (104 a-n); at least an energy source providing electric power to the plurality of propulsors (104 a-n); and a vehicle controller communicatively coupled to each propulsor of the plurality of propulsors (104 a-n), the vehicle controller designed and configured to: calculate initial power levels for the plurality of propulsors (104 a-n), the initial power levels including an initial power level for each propulsor of the plurality of propulsors (104 a-n); detect a present power output capability of the at least an energy source; calculate at least a power demand of the plurality of propulsors (104 a-n) as a function of the initial power levels; determine that the present power output capability is insufficient to match the at least a power demand of the plurality of propulsors (104 a-n); and for each initial power level of the plurality of initial power levels: generate a reduced power level, the reduced power level being less than the initial power level; and direct a corresponding propulsor of the plurality of propulsors (104 a-n) to consume electrical power at the reduced power level. calculate initial power levels for the plurality of propulsors (104 a-n), the initial power levels including an initial power level for each propulsor of the plurality of propulsors (104 a-n); detect a present power output capability of the at least an energy source; calculate at least a power demand of the plurality of propulsors (104 a-n) as a function of the initial power levels; determine that the present power output capability is insufficient to match the at least a power demand of the plurality of propulsors (104 a-n); and for each initial power level of the plurality of initial power levels: generate a reduced power level, the reduced power level being less than the initial power level; and direct a corresponding propulsor of the plurality of propulsors (104 a-n) to consume electrical power at the reduced power level. generate a reduced power level, the reduced power level being less than the initial power level; and direct a corresponding propulsor of the plurality of propulsors (104 a-n) to consume electrical power at the reduced power level.
