报告题目：Condition Monitoring, Diagnosis, and Fault-Tolerant Control in Safety-Critical
Systems - with Applications to Renewable Engineering Systems and Smart Grids
内容简介：Condition monitoring, fault diagnosis, and fault-tolerant control (FTC) in safety-critical systems such as airplanes, nuclear power plants, chemical plants and cars etc., have been progressively and extensively investigated worldwide since the 1970’s. However, the two recent catastrophic accidents induced by the crashes of two Boeing 737 MAX8 airplanes have highlighted again the necessity and urgency for and fault diagnosis and FTC research & development and their industrial applications. The famous blackout that shut down the power in many of the American northeast areas in 2003 have also promoted the development of renewable energy and smart grids in recent years. Electrical microgrids with sustainable distributed power systems, in particular, wind power, are essential to provide service that is reliable, cost-effective, and environmentally responsible. One of key techniques for ensuring the viability and effectiveness of microgrids is to make use of advanced condition monitoring and fault-tolerant control techniques at all levels of power generation, integration into grid, and distribution. In this talk, brief overall view on the challenges and latest developments on condition monitoring, fault detection and diagnosis (FDD), and fault-tolerant control (FTC), and fault-tolerant cooperative control (FTCC) in wind turbines, wind farm, and microgrids are given first. Our latest research works on the above-mentioned subjects will then be introduced as the second part of the talk.

报告题目：Accuracy Enhancement of Industrial Robots Using Visual Servoing
内容简介：Industrial robots are widely used in various applications, from simple packaging tasks to the complex aerospace applications. Most of the manufacturing industries use serial robots for inspection, assembly, welding, drilling, riveting, palletizing and fastening. The relatively low absolute accuracy of industrial robots poses challenge for fulfilling these tasks with high precision demand. There are many factors which affect the accuracy of industrial robots including the manufacturing process, tolerances and inevitable inaccuracies of the components in an industrial robot and the operating environment disturbances. These factors cause the difference between the nominal model of the robot in the controller and the real one. Although robot calibration can improve the accuracy of robots with the help of complex mathematical algorithms and metrology equipment, the resulting accuracy is often insufficient and tends to be subjected to external disturbances. Installing secondary high-accuracy encoders at each robot joint, immediately after the gearbox can be costly and infeasible especially for large number of multiple DOF robots. In the project, two novel, cost-effective, fast and practical sensor-based correction algorithms are developed and implemented to enhance the absolute accuracy of industrial robots using visual servoing techniques. The research works includes on-line pose estimation, dynamic pose correction and dynamic path tracking. Extensive experimental testing on extensively on a FANUC serial robot demonstrated that accuracy of pose correction is enhanced to 0.050 mm for the position and 0.050º for the orientation and the positional and rotational tracking accuracy is improved to 0.1mm and 0.05 º.
