Periodic robust robotic rock chop via virtual model control
Yi Zhang, Fumiya Iida, Fulvio Forni
Robotic cutting is a challenging, contact-rich manipulation task where the robot must simultaneously negotiate unknown object mechanics, large contact forces, and precise motion re…
Passive iFIR filters for data-driven velocity control in robotics
Yi Zhang, Zixing Wang, Fulvio Forni
We present a passive, data-driven velocity control method for nonlinear robotic manipulators that achieves better tracking performance than optimized PID with comparable design com…
Distributed Virtual Model Control for Scalable Human-Robot Collaboration in Shared Workspace
Yi Zhang, Omar Faris, Chapa Sirithunge +3
We present a decentralized, agent agnostic, and safety-aware control framework for human-robot collaboration based on Virtual Model Control (VMC). In our approach, both humans and…
Co-design is powerful and not free
Yi Zhang, Yue Xie, Tao Sun +1
Robotic performance emerges from the coupling of body and controller, yet it remains unclear when morphology-control co-design is necessary. We present a unified framework that emb…
Dissipative iFIR filters for data-driven design
Zixing Wang, Yi Zhang, Fulvio Forni
We tackle the problem of providing closed-loop stability guarantees with a scalable data-driven design. We combine virtual reference feedback tuning with dissipativity constraints…
