6月16日下午，IEEE Fellow，英國赫爾大學Ron J Patton教授應邀在江甯校區伟德 官网4樓會議室做題為“Integrated FE/FTC design of a 3-DOF helicopter system”的學術報告。會議由伟德 官网院長姜斌教授主持，伟德 官网部分師生參加了報告會。

Patton教授首先分析了直升機飛行器的數學動力學模型。然後，提出了集成故障估計器以及容錯控制器的設計方法，對故障估計器以及容錯控制器的參數進行集成全局優化，提高容錯控制性能指标。Patton教授對故障診斷以及容錯控制的深入淺出的講解，給在場師生留下深刻印象。

最後Patton教授與到場的師生進行了交流互動，耐心解答了師生提出的學術問題并與到會老師合影留念。

附：報告人簡介：

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.

報告簡介：

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.
