The Design and Application of a DSP Controller for the Light Axis Stabilization System

In this paper, a DSP controller based on the floating-point digital signal processor, TMS320C6713B, is proposed. It employs the embedded adaptive filter LMS algorithm to control the light axis stabilization system. The DSP controller’s hardware design and software design are presented, and the control system based on the DSP controller is built. The control system’s experiment result is 26.7 dB, and it indicates that the DSP controller has better precision and real-time property.
