Lead controls engineer for the Oxygen Subsystem. Responsibilities included implementing novel control algorithms, managing state machines, improving plant design, tuning actuators, and troubleshooting bugs

Designed a cascaded I-controller to regulate oxygen partial pressure in a system with a 10 minute transport delay

Implemented a gain scheduling algorithm to prevent the mass flow rate controller from amplifying flow perturbations

Performed root cause analysis on Oxygen Subsystem field failures and promptly addressed issues to unblock customer projects

Designed and implemented a real-time resin level detection feature which used force telemetry and digital filtering techniques to precisely determine resin volume during printing within +/- 50 mL

Used field telemetry data queried from AWS relational databases to simulate and test the production resin level detection algorithm against a true positive dataset

Developed and implemented a PID control algorithm to attenuate ground vibrations entering the stage up to 10X more than the existing passive solution

Modeled and simulated isolator control algorithms and digital filters in Python, targeting specifications such as control bandwidth, damping ratio, overshoot, steady-state error, gain/phase margins, and stability

Assisted in the development of stage motion control algorithms by implementing new filter designs, testing and tuning new controllers, and configuring hardware within the motion controller environment

Implemented controllers with C/C++ and verified closed loop performance using telemetry from linear encoders and single axis accelerometers

Designed systems in CREO 5.0 and performed modal analysis in ANSYS to validate derived dynamic models. Corroborated simulation results with results from system identification and hand calculations

A complete redesign of the original printing chassis in which the printing base was widened and lowered

Functional understanding of the mechanisms that operated the printing arm

Knowledge of machine design concepts to size motors, bearings, lead screws, pulleys, and belts

Collaboration with computer and electrical engineers on control of the DC motor and printing arm
