Multilevel Modeling: Developed a hybrid LAAT plant model bridging microscopic aircraft behavior with macroscopic traffic flow dynamics.
Real-Time Simulation: Built a synchronized simulation framework to test and benchmark emerging urban air mobility concepts.
Predictive Traffic Control: Designed model predictive control (MPC) strategies alongside departure and boundary control methods to optimize urban airspace demand and supply.
Hierarchical Control: Implemented hierarchical control algorithms to evaluate controlled aircraft performance under realistic operational scenarios.
Energy-Aware Operations: Integrated an Energy Consumption Model (ECM) into the framework to analyze and minimize macroscopic energy usage and congestion.
Interactive Web Application: Engineered a modular, web-based tool allowing users to simulate, analyze, and optimize low-altitude air mobility scenarios in real time.
Research Development
A modular tool designed to model, analyze, and optimize air mobility scenarios. Integrating MATLAB, CesiumJS, NodeJS, Express, React, and more, this web-based application simplifies user input for simulation settings and presents results in a realistic airspace environment. The simulation tool offers a comprehensive exploration of low-altitude aircraft behavior in the airspace by deploying a novel modeling framework, paving the way for innovative solutions in the future of air mobility.
