| 1 | Design of robust non-fragile H-infinity controllerbased on Delta operator theory显示文摘Considering that the controller parameters are of additive norm-bounded uncertainties when realized,a design method of robust non-fragile H-infinity controller for uncertain system based on Delta operator theory is illustrated in this paper.A sufficient and necessary condition of the existence for the controller is given,which is presented in LMI forms.Finally,the designed method is used in the speed control system of permanent magnet linear synchronous motor (PMLSM).With the designed controller,the resulted speed closed-loop system is still stable and has the expected H- infinity performance even if the sample period is reduced and the parameters of the controller and the controlled object are of variations.The results show that the designed method is effective. | Ruiquan LIN Fuwen YANG Qiugang CHEN | 2007 | 控制理论与应用(英文版)2007，5，4： | 3 |
| 2 | Observer-based H-infinity output feedback control with feedback gain and observer gain variations for Delta operator system显示文摘Considering that the controller feedback gain and the observer gain are of additive norm-bounded variations,a design method of observer-based H-infinity output feedback controller for uncertain Delta operator systems is proposed in this paper.A sufficient condition of such controllers is presented in linear matrix inequality(LMI) forms.A numerical example is then given to illustrate the effectiveness of this method,that is,the obtained controller guarantees the closed-loop system asymptotically stable and the expected H-infinity performance even if the controller feedback gain and the observer gain are varied. | Ruiquan LIN Fuwen YANG Renchong PENG | 2009 | 控制理论与应用(英文版)2009，7，2： | 1 |

| 9 | Integrating climate,biodiversity,and sustainable land-use strategies:innovations from China显示文摘To reverse the accelerating degradation of biodiversity and ecosystem services(‘nature')and climate[1,2],the Convention on Biological Diversity(CBD)and the UN Framework Convention on Climate Change(UNFCCC)will hold major meetings in 2021.We argue that,as a critical priority,countries need to design and implement integrated national strategies to achieve the goals of the three Rio Conventions(including the UN Convention to Combat Desertification-UNCCD)using spatially explicit analyses and policies.This integration can maximize co-benefits and help manage trade-offs to meet the Sustainable Development Goals(SDGs). | Guido Schmidt-Traub Harvey Locke Jixi Gao Zhiyun Ouyang Justin Adams Lin Li Enric Sala M.Rebecca Shaw Sebastian Troëng Jing Xu Chunquan Zhu Changxin Zou Tianxiao Ma Fuwen Wei | 2021 | National Science Review2021，8，7： | 1 |
