HITL Simulation for Actuator Controller

Designed a Hardware-in-the-Loop (HITL) simulation platform for Delta Motion controller. Developed a generalized physics simulation for quick creation of scenarios, including external forces, disturbances, and material changes. Implemented modular plotter classes for various physics, instrumentation, or controller plotting.

Features:

  • 16 analog outputs for instrumentation
  • 8 analog inputs and 8 digital inputs for control input
  • Accurate, real-time simulation with fast physics computations

Combined Sensor Uncertainty Monte-Carlo

Developed a Python report generator for combined sensor uncertainty analysis. The tool provides an object-based system for representing mathematical functions on instrumentation outputs and allows for thermodynamic lookup tables based on instrumentation data. Performed Monte-Carlo simulations on the entire system to assess general uncertainty.

LOX and LNG Tank Overfill Alert

Designed an audible alert system for overfill detection in various propellant tanks. The system operates independently and utilizes a differential pressure switch for overfill signals, with intrinsically safe isolator barriers for operation in hazardous areas.

Manual Abort Control System

Implemented a manual abort control system to provide operators with a direct line to abort or command fire extinguishing systems without relying on network operations. The system uses contact closure over fiber and provides feedback on system status and PLC response.
