Autonomous System Control

CARLA Motion Planning and Control
Behaviour Planner (Intersection scenario), Reactive path planner (Polynomial Spirals planner, Lattice Planner, Optimization), Velocity profile Generator (Trapezoidal Profile + Linear ramp profil)
Vision-based Lane-following Control
In modern transportation system, lane-following motion control is the first-step of self-driving car on road.
Reinforcement Learning Autonomous Overtaking
A Deep Q network-based lane change supervisor and local lane change controller design
Learning-based Localization through Monocular Camera
Multi-Model learning for smooth Georeferenced Tracking from an Uncalibrated Monocular Camera.
Adaptive State Estimation under Model Parameter Error
Model characterization of vehicle must contain errors in dynamical parameters. The parameter error cause inaccurate state estimation from sensors. I am presenting an idea of using Extended Kalman filter to estimate states and parameter simultaneously to produce more accurate state estimation under parameter error.
A Smoother Derivatives Filter Design
A Moving-horizon Quadratic Filter design produces smoother estimation of derivatives of signals than Kalman Filter
Vehicle Dynamics and Model Characterization
Model motion dynamics and estimation parameters.
Remote Driving
Driving and Racing through a remote cockpit
Robust Concensus Control for Multi-agents system
Robust concensus control for multi-agents system in presence of external disturbance and model parameter uncertainty.

Cyber-Physical System Security

An Analytical Frameowrk
Developing concurrent physics-driven and data-driven learning approaches to advance the resiliency of cyber-physical systems in ways that are unattainable using either approach alone
Moving-horizon Attack Generation
How does the attack history affect the feasibility of the attack generation problem at the current time? In other words, is Recursive Feasibility essential for attack generation problem?
Learning Attack Generation
An unified attack generation appoach. It targets any systems, from linear to nonlinear, from power system to autnomous vehicles. It only requires system runtime data.
Anomaly Detection
Leaning based active attack detection and localization. A GPR-based approach and a MLP-based approach.
Concurrent Learning and Resilient Estimation
Enhanced resiliency in cyber-physical systems could be achieved by a statistics-based pruning algorithm coupled with weighted L1 estimator design.
