Hall-effect electric propulsion technology has been widely applied to propulsion systems in small satellite constellations.While offering various advantages，it simultaneously imposes higher demands on ground-based telemetry，tracking，and command resources and manpower so as to meet the health management requirements of satellite constellations.To reduce the demands for ground-based resources and manpower，technologies such as autonomous fault diagnosis and autonomous fault isolation are proposed based on typical on-orbit fault modes of Hall-effect electric propulsion systems in this paper.In view of the limited redundancy in current Hall-effect electric propulsion systems for small satellite constellations，the method of switching the Bang-Bang valve closed-loop control mode is proposed for achieving the recovery functions of partial faults of these systems.The approach is validated by ground-based ignition tests on a Hall electric propulsion system.The results show that any of the selected Bang-Bang valve closed-loop control mode can ensure the reliable operation of the electric propulsion system.Therefore，under reasonable parameter configuration conditions，the system can effectively isolate and recover from faults.Furthermore，this work has preliminarily explored a set of autonomous health management technologies suitable for Hall electric propulsion systems in small satellite constellations.
