Paper Abstract

We present a model for MEMS deformable mirrors (DMs) that couples a 2-dimensional, linear 4th order partial differential equation for the DM facesheet with linear spring models for the actuators. We estimate the parameters in this model using the method of output least squares, and we demonstrate the effectiveness of this approach with data from a 140-actuator MEMS test mirror produced at Boston University. A scheme for robust, computationally efficient open-loop control, which is based on this model, is also presented.
