This paper focuses on the robust attitude control of a novel coaxial eight-rotor unmanned aerial vehicles (UAV) which has higher drive capability as well as greater robustness against disturbances than quad-rotor UAV. The dynamical and kinematical model for the coaxial eight-rotor UAV is developed, which has never been proposed before. A robust backstepping sliding mode controller (BSMC) with adaptive radial basis function neural network (RBFNN) is proposed to control the attitude of the eightrotor UAV in the presence of model uncertainties and external disturbances. The combinative method of backstepping control and sliding mode control has improved robustness and simplified design procedure benefiting from the advantages of both controllers. The adaptive RBFNN as the uncertainty observer can effectively estimate the lumped uncertainties without the knowledge of their bounds for the eight-rotor UAV. Additionally, the adaptive learning algorithm, which can learn the parameters of RBFNN online and compensate the approximation error, is derived using Lyapunov stability theorem. And then the uniformly ultimate stability of the eight-rotor system is proved. Finally, simulation results demonstrate the validity of the proposed robust control method adopted in the novel coaxial eight-rotor UAV in the case of model uncertainties and external disturbances. © 2014 Chinese Association of Automation.

Dear Editor,In the adult brain,the transition from neural stem cell(NSC)quiescence to activation is a focal regulatory point for neural regeneration and dysregulations in the transition lead to brain disorders.1,2 During this transition,both cell cycle states and metabolism including mitochondria undergo extensive reprogramming.A deep understanding of such comprehensive changes is a prerequisite for a holistic picture of physiology and may aid disease combats.

在众多正义理论中,阿玛蒂亚·森提出"能力正义",打破了"程序正义"和"分配正义"一统天下的局面,将人们的关注点从"为何平等"导向"何为平等"。在全球视野下,"能力正义"的出发点是使公民过上有尊严、更体面和愈加美好的生活,阿玛蒂亚·森正是通过关于平等的能力分析路径超越了以往的福利主义和资源主义分析路径,从而彰显出其能力思想的开放性和可行性。能力分析路径包括两个维度:一是将能力作为评估社会发展状况和成员生活质量的指标,二是将个体能力纳入社会公平正义的研究视野。
