My research Lab has TWO main research themes:

• Nonlinear dynamis and control

This is to explore and exploit potential nonlinear benefits in various engineering systems. The research topics include (but not limited to): vibration control (passive, active, metamaterials), energy harvesting, fault detection (or diagnosis), nonlinear system identification (signal processing), frequency domain analysis & design, sensors, actuators, robotic designs, etc.

For vibration control, we focus on a class of X-structures or mechanisms, with a bio-inspired X-structure/mechanism approach, established by the research group in the past years. There are a lot of potential with the X-structures/mechanisms with great applications.

For nonlinear analysis and design, we focus on a parametric characteristic approach, also named as the nonlinear characteristic output spectrum (nCOS) function method, that has been systematically established ever since my PhD study.

We do develop our own methods for other topics such as the SOOS method for vibration based fault detection, the QZS based displacement sensors, the robust control approach to nonlinear system identification, and energy-saving robust vibration control (also crane control) etc.

• Bio-inspired robots: design and control

This is to explore various potential with bio-inspired methods for robot design and control, and we recently focus more on marine robots and applications (Pier inspection, underwater exploration, searching, monitoring, sampling, and photography etc).

For marine robots, we are interested in nonlinear dynamics for new propulsion design to enlarge thrust force and to improve energy efficiency. We are devoted to novel robotic designs to achieve higher mobility, agility, and adaptability in dynamic complex water environments, and to explore omnidirectional and multiple bionic motion modes, and their related modelling, control and realization with new design mechanisms etc. We of course cherish good ideas to obtain excellent underwater sensing, communication, and localization.

Generally, we have interests in exploring all potential bio-inspired robot design and control for specific applications of real world with novel mechanism and control approaches.

I am welcoming R&D talents who share similar research interests to join us as PhD students, research assistants, or postdocs etc.
