6月16日下午，IEEE Fellow，英国赫尔大学Ron J Patton教授应邀在江宁校区威尼斯欢乐娱人城官网33284楼会议室做题为“Integrated FE/FTC design of a 3-DOF helicopter system”的学术报告。会议由威尼斯欢乐娱人城官网3328院长姜斌教授主持，威尼斯欢乐娱人城官网3328部分师生参加了报告会。

Patton教授首先分析了直升机飞行器的数学动力学模型。然后，提出了集成故障估计器以及容错控制器的设计方法，对故障估计器以及容错控制器的参数进行集成全局优化，提高容错控制性能指标。Patton教授对故障诊断以及容错控制的深入浅出的讲解，给在场师生留下深刻印象。

最后Patton教授与到场的师生进行了交流互动，耐心解答了师生提出的学术问题并与到会老师合影留念。

附：报告人简介：

Ron J Patton BEng, MEng, PhD (Sheffield). FInstMC, Sen Mem AIAA, is currently Professor of Control & Intelligent Systems Engineering, University of Hull. He graduated at Sheffield University in Electrical and Electronic Engineering in 1972 and gained Master’s and PhD degrees in Control and Automation at Sheffield in 1975 and 1980.  He held positions at Sheffield Hallam University ［1978-1981］ he became lecturer and senior lecturer in control systems at York University ［1981-1994］.  Ron’s research focuses on robust methods for fault diagnosis and fault-tolerant control (FTC) for process, aerospace and offshore wind turbine/marine energy systems, with a special interest in non-linear systems approaches for control and estimation. He has more than 400 publications, including 123 journal papers and several books and is active in the control community involving FTC.  He is currently a 1,000 Talents Professor at Shanghai Maritime University.

报告简介：

Conventional feedback control designs may result in unsatisfactory performance and stability in the event of component malfunctions or faults. The emerging challenge or goal of Fault tolerant control(FTC) is to accommodate the controller to give a guarantee that the closed-loop system has “admissible behaviour” including tolerance of an expected repertoire of faults, involving joint robustness in control and detection/isolation or estimation.  In FTC all system requirements of functional integrity, reliability, stability and admissible performance must be maintained in the presence of bounded faults. This can be achieved by means of multi-objective design through (1) control robustness, (2) fault compensation/accommodation or (3) fault detection and isolation (FDI) with system redundancy and reconfiguration. The questions to be answered are (a) what are the effects of modelling uncertainty and disturbance and (b) how can the objectives be combined in an integrated way to encompass (a)?

The FTC system and fault estimation (FE) or FDI are each affected by a bi-directional form of uncertainty structure with the uncertainty in FE affecting the FTC performance and the uncertainty in FTC affecting the FE performance. This presentation describes the applicability of a design approach which integrates together these robustness issues into a single-step procedure. The approach can be extended to handle non-linear systems and this is illustrated by an example of a 3-DOF helicopter system in which the non-linear dynamics, disturbance and actuator faults are compensated to give good system performance. The system is designed by taking account of the bi-directional uncertainty along with required performance and fault handling.
