Welcome to COOL

Stable, intelligent and optimal systems.

We are a team of passionate researchers (“COOL Guys”) dedicated to designing the “Brain” of future mobility systems.

Our mission is to bridge the gap between Advanced Control Theory and Real-world Applications. We integrate robust control strategies with embedded AI to create systems that are stable, intelligent, and optimal.

At COOL, we don’t just stop at simulations. We emphasize end-to-end validation, from rigorous mathematical proofs to real-time implementation on actual hardware platforms.

Core research areas

Control theory that runs on real machines.

AREA 01

Advanced Control Theory

Robust Nonlinear Control and Data-driven Control Design for ensuring system stability under uncertainty.

AREA 02

Robot & Mobility

Auto-learning-based control for Robotics, UAVs (Drones), and Defense Applications.

AREA 03

Physical AI & Learning

Light-weight AI (MLP-Mixer) and ESO-based Signal Augmentation on embedded systems for real-time processing.

AREA 04

Reinforcement Learning

Deep Koopman-based Model Predictive Control (MPC) and novel learning frameworks using Disturbance Observers.

Research topics

What we are working on.

Adaptive Neural Network Control

Adaptive Neural Network Control

Intelligent control for highly uncertain and nonlinear dynamic systems. Neural networks identify and compensate unknown dynamics, external disturbances and time-varying changes online, while Lyapunov theory guarantees the stability and safety of the whole closed loop.

Neural approximationLyapunov
Advanced Control for Electric Motors (PMSM)

Advanced Control for Electric Motors (PMSM)

Field-Oriented Control frameworks for precise torque and speed regulation of permanent magnet synchronous motors, with Disturbance Observers and Event-Triggered Control to reject load variations and cut computation and bandwidth.

FOCDOBEvent-triggered
Intelligent Gain Tuning Techniques

Intelligent Gain Tuning Techniques

Adaptive Learning Gain (ALG) algorithms for cascaded control systems. Update laws auto-tune control gains in real time to reach the desired tracking performance across trajectories, robust to unknown loads and parameter variations.
