Nan Li, Shouzhen Zhu, Jinghong Zheng
Rational peak-valley TOU price can change consumer power consumption mode effectively and assure reliable and high efficient operation of power system. Large-scale promotion of distributed generation will have a direct impact on the distribution network and the demand-side response will be faced with...
Illumination Threshold Study of Retinal Security by LED light
Shuyan Ren, Liu Lu, Li Zhao, Yong Sun
Medical experiments using white LED had been done to explain influence on visual function and Electroretinography (ERG) test results have been obtained under different illumination. From the experiments, different character of ERG was changed under different illumination. Compared with the control group,...
Hardware Design of Electro-Mechanical Actuator System
Cheng Wu, Huailin Zhao, Jihong Zhu
As the important executive body of flight control system, the servo aims to drive the control surface deflection according to the position command. This paper makes a hardware design for a digital electric-mechanical servo controller for valve adjustment. Three-phase brushless DC motor(BLDCM) acts as...
