Based on the randomness and uncertainty of short-term traffic volume time series, a grey interval forecasts method combined with threshold value analysis and interpolation analysis is put forward, aim to solve the interval grey model for coping with limited and secondary interval data. According to the stepwise ratio, lots of discussions have been made on threshold value analysis. And then, the upper...
For the performance and accuracy requirements of brushless DC motor speed control system, this paper integrates organically neural network and the traditional PID to constitute brushless DC motor speed control system based on BP neural network self-tuning parameters PID control. The traditional PID controller is used in the beginning several seconds, and then another parameter self-tuning PID controller...
