Reference-model and error-whitening in dynamic compensation for sensors
模型参考和误差白化的传感器动态补偿算法

The dynamic compensator for a sensor can be modeled with a reference model identified by the MSE(mean square error) criterion. However, only the biased estimates of the parameters can be obtained due to the contamination of high level noises in the output/input signals and the limited frequency response range of the compensator. To tackle this problem, the error whitening criterion(EWC) is proposed by which a dynamic compensator can be designed without knowing the dynamic characteristics of sensor. Based on the step-input responses of the sensor and the reference model, the compensator parameters are estimated by the EWC. Finally, experimental results show that this approach is effective.
