Title: Postdoctoral Scholar
Location: National High Magnetic Field Laboratory, Tallahassee, FL
Application Deadline: Open until filled
The National High Magnetic Field Laboratory is seeking a 2-year Postdoctoral Scholar for the field of Electrical Engineering, Controls Engineering, Computer Science, and Systems Engineering who is capable and eager to contribute to the development and engineering of the new controls system for the power supplies.
The MagLab operates four high power and highly stable DC power supplies (14 MW each), which are part of the user facility's infrastructure for operating our world-record resistive and hybrid magnet systems for scientific research. These power supplies convert 12.5 kVAC to a high accuracy variable DC output up to 20 kA at 725 VDC and operate in parallel with each other to supply maximum current. As part of an infrastructure upgrade, the controller for these DC power supplies will be re-engineered using state-of-the-art equipment and controls schemes. This new controller will reduce AC ripple to less than 1 ppm, improve line and load regulation, protect the system against adverse events, and interact with the facility’s own control systems, among other functionality. The successful candidate will gain a detailed understanding of the working mechanism of the power supplies and theirs controls schemes, and will add to our team by specializing in one of two areas:
Track #1 — A control systems expert will use advanced topics of (nonlinear) control theory to design, verify, and implement a state-of-the-art control system using National Instruments LabVIEW FPGA software and hardware. Some component response testing will be required. The resulting system will be robust, well documented, and production-ready. As a controls expert, you would transfer knowledge on relevant topics to the rest of the team to ensure the ability to maintain the system.
Track #2 — A systems engineer or electrical/computer engineer will use NI LabVIEW FPGA and real-time tools as well as hardware and systems engineering skills to realize the controller in physical form. Communication on the engineering work with other team members will be critical since other team members will design individual components of the system.
The candidate will work closely with the core Power Supply upgrade team consisting of two Electronics Engineers, an Electrical Engineer and three Physicists, as well as external collaborators.
Requirement includes a Ph.D. in Electrical Engineering, Controls Engineering, Systems Engineering, Computer Science, or a related field. Extensive experience programming LabVIEW is required. Proficiency in at least one other major programming language is required (LabVIEW, C, and Python are mostly used). Experience with LabVIEW real-time and LabVIEW FPGA programming is highly preferred.
Track #1 requires experience with controls systems, feedback control, and hardware programming (see posting Responsibilities).
Track #2 requires an understanding of electronics designs, communication protocols, safety requirements, and the ability to quickly learn the critical aspects of a complex system and begin contributing to the team right away (see posting Responsibilities).
