Firstly, this article establishes the mathematical models and speed principles of brushless DC motors. Next, it designs fuzzy PID controllers and current adjustors based on the adjusting speed theory and characteristics of brushless DC motors, which form double closed-loops to achieve intellectualized adjustment of brushless DC motors, creating the best effects simultaneously.

OBJECTIVES Variations in sex hormones and the calcium balance can influence bone health in men. The present study aimed to examine the relationship between the calcaneal speed of sound and biochemical determinants of bone mass, such as sex hormones, parathyroid hormones and serum calcium. METHODS Data from 549 subjects from the Malaysian Aging Male Study, which included Malay and Chinese men ...
