EXPERIENCE

George W. Woodruff School of Mechanical Engineering. August 2002-present.

• 
  Invented a novel algorithm that enables simultaneous auto-calibration (learning of the system’s inverse input-state dynamic map) and control of complex nonlinear systems.
  
• 
  Developed an efficient implementation of the novel algorithm using SIMULINK/XPC-Target.
  
• 
  Elaborated a complex dynamic model of a novel two-stage bidirectional Electro-Hydraulic Poppet Valve (EHPV) in SIMULINK and used it for controller experimentation via simulations.
  
• 
  Applied the auto-calibration and control method to 4 independent EHPV’s that resulted in an improved independent metering motion control of hydraulic pistons.
  
• 
  Investigated methods for implementing fault diagnostics with online learning of valve dynamics.
  
• 
  Assembled the hydraulic test bed for controller experimental evaluation and validation. The test bed consisted of a variable displacement pump, manual valves, EHPV’s, a hydraulic piston, and inertial loads. I used CAN bus for control hardware data communications.
