Cyber Physical Human Systems (CPHS) research explores potentially disruptive technologies and novel theories in the integration of sensing, actuation, communication, and computing platforms and algorithms, including robots, sensors, and wireless networks, for advancing human capabilities and improving human lives. CPHS will enable the development of tranformative systems that interact with humans through multiple modalities such as motion, haptic, smell, audio, brain-machine interface, and other new interaction techniques. CPHS will also broaden the advancedment of human capabilities in several realms, including accessing the micro/nano worlds (e.g., single-cell analysis and nano-scale manufacturing), operating in dangerous or inaccessible environments (e.g., monitoring gigantic structures, firefighting, and deep-sea exploration), and improving medical technologies (e.g., rapid drug discovery and ubiquitous healthcare monitoring/delivery). This lecture presents our team’s development of several intelligent sensing platforms based on micro/nano/optical sensors which will enhance diverse CPHS applications spanning from drug discovery to novel interactive technologies and safety monitoring. These platform technologies include human-robot interaction by motion input, mobile human air-bag system, graphene-based motion sensors on wearable flexible substrates, motion recognition for animal drug-testing, robotic palpation sensing fingers for Chinese medicine applications, and optically-induced electrokinetics for single-cell big data analysis.

Human-Robot Collabrative Cyber Physical System Based Learning of Human Welder Intelligences

YuMing Zhang
Professor and James Boyd Professor of Electrical Engineering
University of Kentucky, Lexington, Kentucky, USA

A major challenge in learning human welder intelligence arises from the specular nature of pool surface that disqualifies diffuse reflection-based laser triangulation methods. To overcome this issue, the mirror surface is advantageously used to reflect a laser pattern away from the arc, simultaneously eliminating the arc illumination problem.  To allow welders to freely demonstrate their skills, a human-robot collaborative system has been established where a welder carries a virtual torch, similarly as operating an actual one, without a sensor. The movement is measured at the virtual system and then followed by a robot which carries the sensor and performs the actual welding. The measured weld pool is displayed to the operator at the virtual site such that the welder can observe the change in the operation result to adjust his/her torch movement and other parameters. The true intelligence of the welder is thus contained in and can thus be extracted from the resultant data. To further extend the ability to unconfined environments, an ultra-compact inertial measurement unit (IMU) has been attached to a manually operated torch to monitor its movement and orientation. To ensure the ultra-high precision needed, a foundation has been established to self adaptively cross calibrate the sensors.

Four of his PhD students received the Henry Granjon Prize from the International Institute of Welding (IIW). He currently serves as Lead Principal Reviewer for AWS’ Welding Journal and Associate Editor for IEEE Transactions on Automation Science and Engineering and SME’s Journal of Manufacturing Processes. He has been elected to Fellow of the AWS, ASME, and SME.

Smart Control System for Energy-intensive Equipment

Tianyou Chai
Chair Professor
Center of Automation
Northeastern University, China

China has abundance of mineral resources such as magnesite, hematite and bauxite, which constitute a key component of its economy. The relatively low grade, and the widely varying and complex compositions of the raw extracts, however, pose difficult processing challenges including specialized equipment with excessive energy demands. The energy intensive furnaces together with widely uncertain features of the extracts form hybrid complexities of the system, where the existing modeling, optimization and control methods have met only limited success. Currently, the mineral processing plants generally employ manual control and are known to impose greater demands on the energy, while yielding unreasonable waste and poor operational efficiency. The recently developed Cyber-Physical System (CPS) provides a new key for us to address these challenges. The idea is to make the control system of energy intensive equipment into a CPS, which will lead to a smart control system.
This talk presents the syntheses and implementation of a smart control system for energy-intensive equipment under the framework of CPS. The proposed smart control system consists of three main functions: (i) setpoint control; (ii) tracking control; and (iii) self-optimized tuning. The key in realizing the above functions is the integrated optimal operational control methods to implement setpoint control, tracking control and self-optimized tuning together seamlessly. This talk introduces the integrated optimal operational control methods we proposed.
Hardware and software platform of smart control system for energy-intensive equipment is then briefly introduced, which adopts embedded control system, wireless network and industrial cloud. It not only realizes the functions of computer control system using DCS (PLS), optimization computer and computer for abnormal condition identification and self-optimized tuning, but also achieves the functions of mobile and remote monitoring for industrial process.
Then, using fused magnesium furnace as an example, a hybrid simulation system for smart control system for energy-intensive equipment developed by our team is introduced. The results of simulation experiments show the effectiveness of the proposed method that integrates the setpoint control, tracking control and self-optimized tuning in the framework of CPS.
The industrial application of the proposed smart control system is also discussed. It has been successfully applied to the largest magnesia production enterprise in China, resulting in great returns. Finally, future research on the smart control system is outlined.

Dynamic Visual Servoing in Uncalibrated Environments

Hesheng Wang
Professor
Department of Automation
Shanghai Jiao Tong University, China

Visual servoing is an important technique that uses visual information for the feedback control of robots. To implement a visual servo controller, an important step is to calibrate the intrinsic and extrinsic parameters of the camera. It is well known that the camera calibration is costly and tedious. The calibration accuracy of these parameters significantly affects the control errors. It is desirable to use uncalibrated visual signals directly in controller design. By directly incorporating visual feedback in the dynamic control loop, it is possible to enhance the system stability and the control performance. Dynamic visual servoing is to design the joint inputs of robot manipulators directly using visual feedback. In the design, the nonlinear dynamics of the robot manipulator is taken into account. In this talk, various visual servoing approaches will be presented to work in uncalibrated environments. These methods are also implemented in many robot systems such as manipulator, mobile robot, soft robot, quadrotor and so on.
