OPTIMAL EFFICIENCY CONTROL EQUATION FOR DRIVE SYSTEM WITH FREQUENCY CONTROL

Zhang Chenghui, Tan Zhenyu

CHINESE JOURNAL OF COMPUTATIONAL PHYSICS 1998, 15 (3): 377-384.

Abstract （298）

PDF （294KB）（1116）

For various typical loads including fan pump loads; constant torque loads and constant power loads, the optimal efficiency control equation and its constraint conditions are given using the linearizing expression of the motor. Some simulation computations are provided, and a comparison is made between the results of the new method and those of the model based method for efficiency optimization.

AN IMPROVED WEIGHTING LEAST SQUARES ALGORITHM FOR MATERIAL BLENDING PROBLEM

Zhang Chenghui, Zhang Tiande, Tan Zhenyu

CHINESE JOURNAL OF COMPUTATIONAL PHYSICS 1997, 14 (S1): 512-514.

Abstract （259）

PDF （128KB）（1025）

This paper improves the identification algorithm given in[1] for raw material blending process. The improved algorithm is very suitable for the time varying process and can track the time varying parameter with high accuracy in time. Actual computation examples are provided. Compared with the results of algorithm[1], the new algorithm has a higher identification accuracy, more rapid convergence.
