Research Interests

My research interests mainly focus on the theory and algorithms for estimation, learning, and control of nonlinear dynamical systems, with a strong emphasis on robotics and autonomous systems. I aim to develop mathematically rigorous methods with provable guarantees, while ensuring their applicability to real-world robotic platforms.

Estimation and Observer Theory

This line of research studies real-time state estimation algorithms for nonlinear control systems, with particular interest in convergence guarantees and robustness. I am interested in various topics in this field, including

  • Nonlinear observers (KKL, PEBO, DREM)
  • Adaptive observers
  • Sensorless control and estimation for electric drives
Here is a tutorial on a new observer design approach, parameter estimation-based observer (PEBO).

System Identification and Learning

This theme explores data-driven modeling and learning techniques for dynamical systems, bridging system identification and modern learning theory.

  • System identification for nonlinear dynamical systems
  • Koopman operator–based learning
  • Real-time parameter estimation

Nonlinear Control

I investigate nonlinear control design methods from the following perspectives.

  • Adaptive control
  • Orbital stabilization
  • Passivity-based control (PBC)
  • Contraction analysis

Robotics and Autonomous Systems

My research applies estimation, learning, and control theories to complex robotic systems operating in uncertain environments.

  • Continuum robots: modeling and control
  • Navigation and localization
