An intelligent power management and distribution system is an essential component of future NASA long duration flights in deep space. The current power management system for manned NASA missions in lower earth orbit depends heavily on operators in the ground control center. As mankind ventures into deep space, the existing Power Management and Distribution (PMAD) system will not be able to respond fast enough for ever-changing power requirements in the harsh deep space environment.
The proposed innovation is an autonomous digital-hardware controller with built-in Active Disturbance Rejection Controls (ADRC) for long duration deep space flights. The proposed Autonomous Modular Digital Controller (AMDC) provides high efficient, reliable, fault-tolerant, and intelligent power management for deep space missions.
The following are the relevance and significance of the proposed innovation to the subtopic S3.03:
The current state of art technologies for controlling power electronic switching devices is using mixed analog and digital controls with fixed controller gains. A few of existing all digital controls are microprocessor based controls with a single-thread software written by C programming language. The proposed AMDC utilizes the parallelism of the Field Programmable Gate Array (FPGA) to implement high-speed, multi-threads, all digital hardware, register-based state machines, and intelligent gain controls with active disturbance rejections.
There are many current and future potential NASA applications for the AMDC controlled PMAD systems.
1. Space Vehicle Power Management and Distribution (PMAD) System: to provide stable, clean, and reliable power to the associated on-board systems.
2. Scientific Researches Missions in Deep Space: having the AMDC system can help speed up development of future deep space propulsion.
3. All Electrical Airplane: AMDC provide efficient and safe method of powering the drive and life-support systems.
4. Unmanned air vehicles: AMDC allows true UAV applications with autonomous PMAD system.
1. High Efficiency Renewable Energy: the AMDC will have the basic building blocks to convert renewable energy.
2. Aerospace and Defense: AMDC is ideal to manage complex electrical systems.
3 Medical Power Systems: The fault tolerant and stability of AMDC would allow modules to be used in life-critical applications.
4 Large Servers and Computer Data Centers: AMDC can benefit power critical systems such as server farms, scientific systems, and supercomputers.
