Discrete-Time Domain Analysis of a Two-Axis Beam Deflector.

摘要

The state-variable feedback model of a two-gimbal planar-mirror optical tracking system is simulated in both the continuous-time and discrete-time domains using a digital-machine simulation language called MIMIC. Four open-loop models are analyzed with respect to a conventional set of performance indices. The required model parameters are provided by an auxiliary program called POLSLVR which is specifically tailored for this problem. Emphasis is placed on obtaining acceptable solutions requiring the least amount of system gain with a relatively rigid sampling time specification to reduce the effects of a base-motion disturbance.
