Non-Linear Adaptive Optics (NLAO)

Nutronics, Inc. and Montana State University propose to develop an approach for non-linear control of hysteresis and incorporate (if necessary) integrated Multi-Input-Multi-Output real time control with this capability.Our control systems already include a proven high speed real time control approach to determine the optimal set of actuator commands that satisfy inter-actuator stroke limitations.Our control solution for accommodating inter-actuator stroke limitations does not impose any limitations on the real time control bandwidth as with standard spatial filter based solutions.The same nonlinear control paradigm used for inter-actuator control will also be used for hysteresis compensation. During the Phase 1 effort our team will develop an integrated temporal response and hysteresis model for the DM to enable testing our algorithms against a simulated hardware element.In addition, our team will seek opportunities for hardware validation and test leveraging other ongoing efforts if possible.Our team will develop a detailed conceptual design for implementation of the NLAO algorithm in a future Phase 2 effort.
