Ajay — Controls Engineer

Assisted in the installation, operation and troubleshooting of various Festo MPS (modular production system) stations. Programmed Allen-Bradley PLCs that control processes (such as material handling systems, multi-position servo etc.) and automate tasks. Developed HMI/SCADA interface for a water filtration system. Carried out off-line programming of ABB robots using ABB RobotStudio. Programmed motion control systems and robotic manipulators for pick-and-place operations. Acquired foundational knowledge in all of the programming languages defined in IEC 61131-3 standard.

Performed stress analysis of metallic airframe structure and its components by hand calculations and FEA.

1) Collision avoidance with dynamic obstacles exhibiting periodic motion • Applied the collision cone method for collision avoidance between objects exhibiting periodic motion. • Carried out several numerical simulations for different scenarios using MATLAB. • Performed a comparison of the trade-offs between conflict avoidance cost and the time to execute avoidance maneuver. 2) Boat controller using neural networks • Created a neural net pseudo-inverse controller for a boat operating in a 100m×100m area. 3) Structural and flight dynamics of flexible launch vehicles • Collaborated with team members to develop a dynamic model of a generic, medium size, three-stage, flexible launch vehicle. • Modeled propellant slosh dynamics using the pendulum model. • Carried out calculations for damping of lateral sloshing of propellants in fuel tanks.
