EXPERIENCE

September 2018-

November 2018 Nordson EFD

Control Systems Engineer (Contract)

Developed control strategies to improve the precision and repeatability of fluid and ceramic dispensing equipment.

Applied Infinite Impulse Response techniques to dampen undesirable resonance frequencies which tend to

degrade system performance.

Control development and analysis based upon applicable MATLAB toolboxes.

Provide weekly status updates to management to insure compliance with stringent deadline constraints.

November 2015-

April 2018 Electro Standards Laboratories

Developed MATLAB scripts to simulate aircraft arrestment performance under adverse landing conditions aboard aircraft carriers.

Established linearization strategies to evaluate robustness levels

in the design of an optimal controller.

Sensitivity techniques in the determination of potential performance degradation or system failure under all combinations of potential failure modes. This technique is less computationally intensive as is Monte Carlo.

June 2012-

May 2013 MIT Lincoln Laboratory

Systems/Test Engineer (Contractor)

Improved Signal-to-Noise Ratios of a low power laser communications system. This resulted in better signal integrity and acquisition time.

Designed and developed a thermal isolation chamber to evaluate the thermal characteristics of a low powered laser communication beam-steering system.

Played an integral role in the development of a laser communication platform stabilization system using IFOGs for disturbance rejection and improved pointing accuracy.

November 2004 – Charles Stark Draper Laboratory

May 2011 Senior Technical Staff Member

Developed Kalman filter equations in MATLAB to process TRIDENT II guidance data and to verify that the Prelaunch navigation estimates of position, velocity and attitude were consistent with pre-determined guidelines.

Modeled missile guidance gimbal servos to determine attitude errors prior to launch. Unique control parameters were estimated for each system.

Developed methodology to minimize errors attributed to pipeline A/D and D/A non-linearities.

Designed and implemented Electromagnetic Radiation Susceptibility tests for TRIDENT II Guidance & Navigation system electronic modules. This required the design and construction of Helmhottz coils.

September 2011-

October 2011 UTC Aerospace (formally BF Goodrich)

Systems Engineer (Contractor)

Contributed toward the improvement in the pointing accuracy for a RECCE project.

Developed test plans and procedures to evaluate the performance capabilities of the RECCE device.

August 1990- Hexagon Metrology (formally Brown & Sharpe Manufacturing)

February 2004 Senior Control Systems Designer

Designed motion control systems for coordinate measuring

machines for worldwide applications using MATLAB to improve position accuracy and throughput.

Advanced the capability of the embedded servo code using Microsoft Macro Assembler.

Lead Universal Controller Design Project for Italian and German subsidiaries resulting in a unified design for global Hexagon machines

Developed all-digital controller using state-space observer techniques to replace conventional tachometer-based systems

Created computer simulation tools in C and MATLAB to evaluate machine performance in the presence of friction, backlash and hysteresis leading to successful, next generation control.

Developed and simulated all control algorithms using MATLAB with SIMULINK

Developed measurement application programs for UNIX-based operating systems

Specified and evaluated DC motor drives for state-of-the-art Coordinate Measuring Machines
