Simulation Analysis of Stereo Garage Control Algorithm based on ADRC
Yongde Zhang,Tongning Shi,Lei Wang,Jingguo He,Daifu Tian 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.6
With the rapid growth of car ownership, "parking" has gradually become the hot issue of society in general. At present, people widely used stereo garage because it took small area, which had a high space utilization, and convenient operation. However, due to internal instability of three-phase asynchronous motor parameters and load disturbance factors such as fluctuations, it led to a poor robustness of the control system. Therefore, we build a system of first order mathematical model using Simulink based on Active Disturbance Rejection Control (ADRC) and made the simulation analysis by the analysis of the controller structure and algorithm. And through the comparison with the traditional PID control, we implementated the signal fast response optimization design and control overshoot.
Identification and Epigenetic Analysis of a Maternally Imprinted Gene Qpct
Jing Guo,Qiong Wu,Hongjuan He,Qi Liu,Fengwei Zhang,Jie Lv,Tiebo Zeng,Ning Gu 한국분자세포생물학회 2015 Molecules and cells Vol.38 No.10
Most imprinted genes are concerned with embryonic development, especially placental development. Here, we identified a placenta-specific imprinted gene Qpct. Our results show that Qpct is widely expressed during early embryonic development and can be detected in the telecephalon, midbrain, and rhombencephalon at E9.5-E11.5. Moreover, Qpct is strikingly expressed in the brain, lung and liver in E15.5. Expression signals for Qpct achieved a peak at E15.5 during placental development and were only detected in the labyrinth layer in E15.5 placenta. ChIP assay results suggest that the modification of histone H3K4me3 can result in maternal activating of Qpct.
