Abstract

In this paper, the design and control of a thermal stabilizing system for an Optomechanical Uncooled Infrared Imaging camera is presented, which uses an array of MEMS bimaterial can tilev erbeams to sense an infrared image source. A one-dimensional lumped parameter model of the thermal stabilization system w as deriv ed and experimentally v alidated. A model-based discrete time Linear Quadratic Gaussian Regulator(LQGR) control scheme, with a stochastic ambien t noise model, w as implemerted. The control system incorporates a reference model, which generates desired reference temperature trajectory, and integral action to respectively diminish overshoots and achieve zero steady state error in closed loop. Simulation results show that the designed LQGR con trailer is able to enhance ambien ttemperature low frequency disturbance attenuation by more than 50dB. The con trol system is able to regulate the focal-plane array (FPA) temperature with a standard deviation of about 100/tK, in spite of ttfact that the temperature measuremen t noise has a standard deviation of 1mK.
