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)
—This paper proposes an improved decision based feedback scheme for Single carrier transmission with frequency domain equalisation (SC-FDE) communication systems. The approach exploits a processed version of the decisions made in symbol estimation such that the optimisation problem of the equalisation parameters in the frequency domain and the time domain(More)
