Study on a Method to Improve the Stability of the Sensor Signal Based on Pd Controller
Abstract:
In order to solve the high frequency oscillation generated from the
video signal of the camera, the paper proposes a method to improve the stability
of high frequency oscillation of common sensor signal which means the high frequency
oscillation signal generated from the sensor module can increase the phase margin
of the unstable signal through PD controller, thus produces a stable video signal
and then through the circuit of AGC (Automatic Gain Control), the automatic
compensation of the frequency can be achieved and finally the fourth-order low-pass
circuit is used to meet the requirement of cutoff frequency of the sensor signal
processing and the stability of the signal and the high frequency performance
can be ultimately improved.
