Digital Twin — Variable-Speed Electric Drive

Electric-drive digital twin using state-space modelling, numerical integration, H-bridge representation, cascade PI control and signal analysis.

Digital Twin — Variable-Speed Electric Drive
PROJECT CONCEPT VIEW

The illustration separates the simulated drive from its digital representation: electrical and mechanical states are propagated through the model while the cascade PI loops shape current and speed response. The project is simulation-first, so the physical bench shown here is illustrative rather than a claim of real-time hardware deployment.

Problem

A drive model is useful only when the machine, converter and controller can be inspected together.

Solution

A compact simulation chain connecting the model, converter representation and cascade PI control.

Build path

  1. Build the state-space model.
  2. Represent the H-bridge stage.
  3. Tune the cascade PI control.
  4. Analyse the simulated response.

Discussion

The project keeps the control action understandable from assumptions to simulated response.
