This paper summarizes the study progress on the impending earthquake prediction by Chinese scientists from the method of multi-subject intersection and the internal and external factors coupling. Depending on very hard work during recent years, they get some important signals of predicting impending earthquakes, including the anomalies of infrasonic sound wave, crustal stress, behavior of budgerigars, general geoelectric, geomagnetic, satellite heat infrared and high frequency gravity pulsation.

文章综述了中国科学家从多学科交叉和内外因耦合的科学途径，已在大地震临震信号方面获得了次声波异常、地应力突跳、虎皮鹦鹉跳跃异常、地电和地磁异常、卫星红外异常、重力高频脉冲等临震预测的手段。

In this paper, a novel control strategy which contains a simple and practical fuzzy proportional derivative unit combined with an integral unit and an acceleration damping unit was developed. This configuration preserves the linear structure of the conventional state feedback controller, but has variable gains: the proportional and derivative gains are nonlinear functions of their input signals, which have self-tuning capabilities using human experience and knowledge.
