QI XIONG

Master’s student in Electrical Engineering at UNSW, with a Bachelor’s in Automation. Proficient in MATLAB/Simulink, AutoCAD, and system modeling. Seeking an EE internship in power infrastructure and property to apply distribution network analysis and electrical design skills.

Grid Harmonic Detection Design | MATLAB/Simulink (Jun–Jul 2025)

• Developed a time-domain synchronous-reference detector using Clarke-Park transforms and discrete PI loops
• Configured digital filters and loop dynamics to ensure robust amplitude, frequency, and phase tracking under harmonics, phase jumps, and voltage sags
• Automated simulation data logging and MATLAB-based postprocessing for performance validation

UAV-Assisted Wireless Communications Optimization | Python, Gym & Stable-Baselines3

• Designed and implemented a Gym-based simulation environment in Python to model an aerial base station (ABS) with multi-antenna beamforming.
• Formulated UAV trajectory and beamforming as an MDP and applied deep RL algorithms (PPO, SAC, DQN via Stable-Baselines3) to jointly optimize flight path and signal transmission.
• Achieved significant increase in cumulative downlink throughput for N ground users over 200–300 s missions under given speed (10–30 m/s) and power constraints.
• Visualized results with plots of throughput vs. trajectory, training convergence curves, and baseline comparisons.
