About

I am a control engineer focused on high-performance motion systems. My work connects mechanical dynamics, frequency-response identification, controller design and real-machine validation — the full chain from a differential equation to a machine that meets its spec.

This site is not a résumé and not a blog. It is an engineering evidence base: each project documents a real class of problem, the model behind it, how it was measured, what was decided and why, what failed, and which parts became reusable tools.

How I work

Model first

Every control problem starts as a physical model — masses, stiffnesses, friction, contact — before any gain is touched.

Measure honestly

FRFs with coherence, repeated runs, condition-number checks. If the measurement cannot be trusted, neither can the design.

Validate on the machine

Simulation verifies logic; only machine tests verify engineering. Every project page separates the two explicitly.

Make it reusable

Methods become scripts, scripts become tools. The engineering tools on this site are the reusable residue of real projects.

Current focus

  • Bonding-head Z-axis force control
  • MIMO FRF identification
  • Motion-system sizing methodology
  • Contact dynamics
  • Engineering analysis tools

Data policy

Projects on this site involving employer or customer systems use sanitized or normalized data only: no source code, no exact device parameters, no customer names, no internal screenshots, no un-sanitized test data. Where a real value cannot be published, it is marked sanitized, normalized, TODO or TBD — never replaced with an invented number.
