controls-engineering

A professional, industry-standard automated control system designed in OpenPLC Editor v4 using IEC 61131-3 Ladder Diagram (LD) logic. This project demonstrates core industrial automation concepts: latching circuits, safety interlocking, signal filtering via timers, and live status feedback indicators.

Reference PLC-style conveyor state machine with interlocks and fault handling [Structured Text]. Demonstrates HMI concept and operator interaction layer.

My implementation of LQR and MPC control for the classic inverted pendulum controls problem.

Internal-style Python tool for generating practical automation commissioning checklists, emphasizing safety, interlocks, startup, and validation over configurability or polish.

PLC-controlled industrial automation cell simulator with OpenPLC, Modbus TCP, C++ digital plant simulation, HMI, fault handling, and deterministic control logic.

This tool helps automation engineers and reliability specialists simulate fault occurrences, log events, and produce basic summaries for improved reliability and troubleshooting. It's designed to support reasoning about failure patterns and post-incident analysis.

Studio 5000 PID temperature control loop using the PIDE instruction with auto/manual mode, setpoint ramping, output limiting, autotune, and a simulated thermal process.

Curated, verified library of 1,000+ Rockwell / Allen-Bradley and partner-vendor manuals, organized by device family for controls engineers.

Personal engineering portfolio website with live project demos

Personal website and engineering portfolio for Miller Powell, focused on electrical engineering coursework, manufacturing systems, and personal hobbies.

Modular Beckhoff TwinCAT 3 conveyor sorting system featuring Structured Text, state-machine control, fault diagnostics, motion simulation, manufacturing analytics, and a SCADA-ready data layer.

A catalogued, verified, snapshot backed index of the technical documentation behind automation and industrial power: PLCs, drives, protocols, silicon, instrumentation, switchgear, and the standards that govern them. Every row states how far it was actually checked. Built in public by a field service engineer.
