报告题目:On Fault-Tolerant Control (FTC) and Fault-Tolerant Cooperative Control (FTCC) of Unmanned Systems and Their Applications(无人系统的容错控制与容错协同控制及其应用研究)

报告人:张友民 教授

单位:Concordia University (Canada)

报告时间:2017627日(周二)上午9:30-10:30

报告地点:中心楼二楼教育部重点实验室会议室

报告摘要:Unmanned systems including Unmanned Aerial Vehicles/Systems (UAVs or UASs), Unmanned Ground Vehicles (UGVs) and Autonomous/Driverless Cars, as well as Unmanned Surface/Underwater Vehicles (USVs/UUVs) are gaining more and more attention during the last a few years due to their important contributions and cost-effective applications in several tasks such as surveillance, sense, search, rescue, agriculture, forest and environment, pipelines and powerlines, military and security applications. On the other hand, health management and Fault-Tolerant Control (FTC) of manned aircraft have a long history since the initial research on self-repairing flight control systems in US Air Force and NASA begun in mid-1980s. However, due to safety concern of manned aerial vehicles to the pilot, experimental test and further practical research and development have been limited. Benefited from the recent and significant advances and developments of UAVs, development and application of autonomous, fault-tolerant, and cooperative control techniques have been emerged and developed quickly in recent years, since UAVs provide a cheap and operative experimental testbed for development, implementation, testing and validation of the newly developed autonomous, fault-tolerant, cooperative and even the latest Fault-TolerantCooperative Control (FTCC) techniques.

 

In this talk, brief review on the development of autonomous unmanned aircraft systems and challenges on autonomy and fault tolerance of unmanned systems will be given first, then the latest development and current research work on FTCC with applications to autonomous quadrotor helicopter UAVs, wheeled mobile robots/ground vehicles testbeds and unmanned surface vehicles developed in collaboration with industry at Concordia University, as well as applications to wind turbines/farm in the renewable energy field, will be introduced.

报告题目:Necessary and Sufficient Condition of Linear Strong Structural Controllability and Observability of an n-Link Underactuated Revolute Planar Robot

报告人:忻欣 教授

单位:Okayama Prefectural University (Japan)

报告时间:2017627日(周二)上午10:30-11:30

报告地点:中心楼二楼教育部重点实验室会议室

报告摘要: The concept of strong structural controllability and observability, which means that all systems with the same structure are controllable and observable has attracted renewed attention recently in studying complex networks. In this talk, we will introduce our new results of the linear strong structural controllability and observability of complex networks by studying an n-link underactuated revolute planar robot with all the links moving in the same vertical plane, which has received considerable research interest recent years. Our previous study shows that such a robot is linearly controllable and observable, around the upright equilibrium point (UEP), where all the links are in the upright position, regardless of its physical parameters, if the first or the last joint is active. In this talk, first, when the robot only has an active intermediate joint or active intermediate nonadjacent joints, we prove that the robot is linearly strongly structurally uncontrollable and unobservable around the UEP by showing illustratively that there always exists a set of physical parameters that renders the robot linearly uncontrollable and unobservable around the UEP. Second, when the robot only has two active intermediate adjacent joints, without making any assumption on the physical parameters of the robot, we prove that the robot is linearly strongly structurally controllable and observable around the UEP. Thus, the robot with its first and last joint being passive is linearly strongly structurally controllable and observable around the UEP if and only if there are at least two active adjacent joints among (n-2) intermediate joints. We present new insights into the linear controllability and observability of such a robot with different actuator-sensor configurations of multiple actuators and encoders.

报告题目A Communication/Control Co-design Paradigm for Networked Control Systems (Joint work with Prof. Li Qiu, Prof. Guoxiang Gu, and Mr. Songbai Wang)

报告人:陈伟 博士后

单位:UC Berkeley (USA)

报告时间:2017627日(周二)下午14:30-15:30

报告地点:中心楼二楼教育部重点实验室会议室

报告摘要We propose a communication/control co-design paradigm to study networked control systems. The essence of this new paradigm is to allow the communication network to be jointly designed with the controller design. In this talk, two different communication/control co-design approaches would be discussed, i.e., the channel/controller co-design and coding/control co-design. In the channel/controller co-design, we find the minimum total channel capacity required for stabilizability given in terms of the topological entropy of the plant. In the coding/control co-design, the MIMO technology recently developed in communication theory has been utilized for information exchange. A necessary and sufficient condition for the networked stabilizability is obtained given in terms of a majorization relation.
