Frontiers of Information Technology & Electronic Engineering 2015年第7期16卷 579-593页

This paper presents a control algorithm for push recovery, which particularly focuses on the hip strategy when an external disturbance is applied on the body of a standing under-actuated biped. By analyzing a simplified dynamic model of a bipedal robot in the stance phase, it is found that horizontal stability can be maintained with a suitably controlled torque applied at the hip. However, errors in the angle or angular velocity of body posture may appear, due to the dynamic coupling of the transla- tional and rotational motions. To solve this problem, different hip strategies are discussed for two cases when （1） external dis- turbance is applied on the center of mass （CoM） and （2） external torque is acting around the CoM, and a universal hip strategy is derived for most disturbances. Moreover, three torque primitives for the hip, depending on the type of disturbance, are designed to achieve translational and rotational balance recovery simultaneously. Compared with closed-loop control, the advantage of the open-loop methods of torque primitives lies in rapid response and reasonable performance. Finally, simulation studies of the push recovery of a bipedal robot are presented to demonstrate the effectiveness of the proposed methods.

紫外探测器在火灾预警、导弹跟踪以及紫外线杀菌消毒的剂量检测方面有着很重要的作用,与人类生活息息相关.随着探测系统集成化的发展,对探测器的尺寸、能耗等方面的要求越来越严格,需要外加电源工作的传统探测器已经不能满足这样的要求.于是本文提出了一种基于NiO/GaN p-n结的紫外探测器.利用磁控溅射的方法,在高质量的n-GaN膜上(由金属有机化学气相沉积生长在蓝宝石衬底上)沉积一层p-NiO,构建了NiO/GaN p-n结,在±0.5 V下显示出明显的二极管整流特性.利用结区产生的内建电场,器件可以在没有外加偏压的条件下工作.0 V下对365 nm的紫外光显示出272.3 mA/W的响应度以及高达2.83×10^(14)Jones的探测率.得益于薄膜良好的结晶性,暗电流低至10^(–10)A,开关比>10^(3),同时响应速度达到31 ms.这些优异的性能显示出了基于NiO/GaN p-n结的器件在紫外探测领域广阔的应用前景,为未来智能化集成发展提供了新的思路.
