This paper focuse on the design and implementation of speed-current double closed loop for permanent magnet brushless DC motor(BLDC). In analyzing the characteristics of the fuzzy controller, The new form of whole fuzzy controllers are proposed. Speed loop worked with a fuzzy adaptive PID controller is the main loop of the system. As the current loop is inner loop which is a servo system, The fuzzy...
Shoeprints are frequently acquired at crime scenes and can provide vital clues for investigation. How to retrieve the most similar shoeprints available in the dataset to the highly degraded query crime scene shoeprint is a challenging work. Some existing shoeprint retrieval algorithms cannot work well with highly degraded shoeprint image on a large scale dataset, and the results are not well correlated...
