| Abstract: | Due to no repetition, sensitive and random of chaos dynamics, chaos searching is imported to BP neural network. New chaos optimal BP algorithm has global convergence, no local minimum. A soft sensor of coal load measuring based on chaos optimal BP neural network is constructed in DPU. Computer simulation results demonstrate that the soft sensor is effective and instructive in field operation. |
