|Advanced control of electric vehicles and development of wireless in-wheel motors
Prof. Hiroshi Fujimoto
|Electric vehicles (EVs) have attractive potential not only for energy and environmental performance but also for vehicle motion control because electric motors have quick and measurable torque response. The speaker’s laboratory has developed a completely original EV which has active front and rear steering systems. We installed high-torque direct-drive in-wheel motors and lateral force sensors to all wheels.
In the first part of this talk, our recent studies on advanced motion control and autonomous driving to enhance safety, driving comfort, and energy efficiency will be briefly introduced. In the second part, a new type of in-wheel motor, which receives electric power by wireless power transfer using magnetic resonance coupling and control signals by wireless communication, in order to avoid the disconnection of power and signal cables have been developed. This system is called Wireless In-Wheel Motor (W-IWM). In this system, it is also possible to directly transmit power to the in-wheel motor without cables from underground coils for dynamic charging in order to extend the cruising range. This talk introduces the overview and design methods of the W-IWM. We also evaluate the characteristics of the W-IWM when installed on an electric vehicle and demonstrate its effectiveness by driving tests.Hiroshi Fujimoto earned his Ph.D. degree in the Department of Electrical Engineering from the University of Tokyo in 2001.

|Can we synthesize robot mechanisms creatively without any baseline design?
Distinguished Prof. Yoon Young Kim
|Mechanisms covert an input motion (force) to the desired motion (force). They critically affect the mechanical performance of machines equipped with them. However, it is challenging to design robot mechanisms that successfully generate elaborately-planned motions without big data or many trials and errors. We have looked for a new autonomous (automatic) mechanism synthesis method.
In this talk, we address the following issues:

|Modeling ionic polymer metal composites: where we are and where we should be
Prof. Maurizio Porfiri
|Ionic polymer metal composites (IPMCs) are a promising class of soft active materials. Their high compliance, low actuation voltage, and ability to operate in wet environments have motivated two decades of intensive research on IPMC actuators. While we have witnessed several breakthroughs in the technology of IPMCs, from additive manufacturing of IPMCs to IPMC-based robots, our understanding of the physical underpinnings of their actuation remains elusive. There is a paucity of pedictive, continuum physically-based models to investigate IPMC actuation and sensing. Presently, the literature relies on either black-box lumped models, whose parameters are experimentally identified from data, or phenomenological distributed models, constructed upon classical beam theory. In this sense, we know little about multiaxial deformations elicited by counterions’ diffusion and electromigration through the ionomer. In this talk, we discuss recent progress by my group on a physics-based modeling framework that describes the complex chemoelectromechanical behavior of IPMCs. The proposed framework successfully resolves interface phenomena taking place in the vicinity of the electrodes along with a number of key non-idealities that challenge our intuition and pave the way to new design approaches.

|Cyber-physical security of networked control systems
Prof. Henrik Sandberg
KTH Royal Institute of Technology, Sweden
|Reports of cyber-attacks, such as Stuxnet, have shown their devastating consequences on digitally controlled systems supporting modern societies, and shed light on their modus operandi: First learn sensitive information about the system, then tamper the visible information so the attack is undetected, and meanwhile have significant impact on the physical system. Securing control systems against such complex attacks requires a systematic and thorough approach. We provide an overview of recent work on secure networked control systems centered on a risk management framework and its main stages: scenario characterization, risk analysis, and risk mitigation. In particular, we shall consider malicious attacks on key security properties such as confidentiality, integrity, and availability. Then we focus on specific cyber-physical attack scenarios in control systems and mitigation strategies currently being investigated in our research group.
