Embodiment Construction

[0019] Such as figure 1 As shown, the present invention comprises: fast mirror, laser light source, position-sensitive sensor, base, power amplifier, low-pass filter, band-pass filter, DSP control card, position-sensitive sensor is positioned at base, and laser light source shines on Reflected on the fast mirror to the position-sensitive sensor, the external disturbance source is transmitted from the base to the position-sensitive sensor, the spot of the laser beam moves relative to the position-sensitive sensor, and the position-sensitive sensor generates a voltage of relative displacement, which passes through the band-pass filter and the external The disturbance signal of the signal enters the DSP control card, and the DSP control card collects the two signals and undergoes A / D conversion, then performs real-time analysis and control calculation through the embedded LMS algorithm, and then converts the digital quantity to be controlled into an analog quantity and outputs it ...

Description

technical field [0001] The invention relates to a real-time active vibration control system for a fast reflector, in particular to a real-time active vibration control system for a fast reflector based on a DSP control card, which is used for real-time active vibration control of a one-degree-of-freedom fast reflector. Background technique [0002] As a precision tracking technology developed in recent years, fast mirrors are used to control the direction of the emitting and receiving optical axes, and correct the change of the beam arrival direction, that is, the correction of the overall tilt of the beam wavefront distortion, which is far from Do not open the control system. Most of the existing fast mirror control systems are composed of industrial control machines, A / D and D / A cards. This kind of control system is bulky, has poor anti-interference ability, relatively low control accuracy, and does not have real-time and fast control functions. . Contents of the invent...
