Development of Comprehensive Testing Apparatus for Mine Fixed Equipment

Yang Shi-xing, Xue Chao-mei

1999, 25(5): 17-18.

<Abstract>(38)

Abstract:
Hoist, ventilator, air pressure machine and water pump are main fixed equipment which play important roles in coal mine production and consume most of the power. Traditional testing by manual is hard to satisfy the demands of determining operating status and technical parameters. Newly developed testing instrument is able to test parameters of 4 equipment with high testing efficiency and accuracy that is unparalleled by using traditional way.

Research in A Type of Expert Model Algorithmic Control with No Static Error

Xue Yun-can, Huang Guo-ming

1999, 25(5): 19-22.

<Abstract>(56)

Abstract:
In this paper, a predictive control algorithm called “Expert Model Algorithmic Control (EMAC)” is studied. Special attention is paid to its robustness with parameter variations and variable time delay. Static error has been eliminated. Good performance is shown by comparing EMAC with MAC. EMAC has no complex computation and it is very easy to be used in the industrial control.
