Filter type for smoothing sensor data (P-CHAN-00825)

P-CHAN-00825

Filter type for smoothing sensor data

Description

Sensor values may be noisy. The oscillation tendency can better be suppressed by using a suitable filter . You can select the following filter types for distance control:

  • DEFAULT: Moving averaging filter where P-CHAN-00800 = 4
  • MOVING_AVERAGE: Moving averaging filter
  • LOWPASS: Low-pass filter
  • KALMAN_MA: Kalman filter with prediction from averaging filter
  • EXPO_MEAN: Exponentially weighted averaging filter
  • KALMAN_EXPO: Kalman filter with prediction from exponentially weighted averaging filter
