To reveal the change law of the simulation error of grey model GM(1,1) with translation transformation applying on the original sequence, in this paper, the experiments based on 55 real world data sequences have been conducted to study how the translation transformation influences the grey models' error characteristics. The results show that a larger translation transformation can make the total error...
Bispectral index (BIS) is a popular technology widely used in hospitals to monitor depth of patients' anesthesia during surgeries. Maintaining a proper, steady state of the patient's BIS level is critical for patient safety. In this paper an autoregressive moving average model is implemented on patient BIS data for the prognosis of the depth of anesthesia. This prognosis will enable anesthesiologists...
A model set identification approach is presented for Hinfin robust control design of Hydraulic Flight Motion Simulator servo system, which suffers from various uncertainties, such as parameter uncertainty, high frequency unmodelled dynamic uncertainty, and so on. The identification approach consists of two steps. To be exact, the first step is nominal model parameter identification, and then model...
Shengli refinery plant process middle-east crude oil, the equipment is exposed to wash erosion seriously. The elbow on the entrance of the atmospheric distillation tower top exchangers always leak for eroding. Measured the thickness of elbow by ultrasonic thickness meter every month, established GM (1, 1) model with grey system theory, the average relative error is 1.8959%, model passed error check,...
