Fast steering mirrors are used in many optical system applications, ranging from image tracking and scanning, to laser material processing, to jitter stabilization in optical communication. This paper presents a systematic approach to the modeling and feedback control design for a high performance fast steering mirror used for image scanning in a(More)
In digital system, a full-closed-loop configuration using a tachometers and an analog-digital converter with low resolution results in bad speed control and therefore influences the positioning performance in a high-precision positioning system. However, on the other hand, speed information cannot be accurately obtained through the encoder using traditional(More)
