Detailed Train Propulsion Simulink Model
Budget: $14 – $30 NZD
I need a complete Simulink representation of a train’s traction & propulsion chain. The focus is on detailed component behaviour, not a high-level sketch, so every block has to capture dynamics and losses that matter on the rails.
Scope
• Electric motor: build or adapt a physics-based induction / permanent-magnet model with efficiency map, torque-speed curve, thermal limits and inverter interface.
• Traction control system: include slip detection, torque limiting, PWM inverter logic and speed/torque regulators so I can try alternative control strategies later.
• Power supply: model a typical catenary or third-rail source with voltage sag, line impedance and regenerative feedback so energy flow is realistic.
Simulation goals
The model should accelerate a standard consist from 0–300 km/h under a 25 kV AC profile, log current, voltage, wheel torque and motor temperature, and finish without errors in MATLAB/Simulink R2023b (or tell me the exact version you use).
Deliverables
1. .slx file plus any custom libraries / scripts
2. Quick-start note (parameters, how to run, expected plots)
3. Short PDF or Word brief explaining assumptions, equations and where each parameter lives
Acceptance criteria
• Runs out-of-the-box on my machine
• Key curves (speed, current, torque) track published reference data within ±10 %
• Blocks and signals are clearly labelled for future extension (braking, passenger comfort modules, etc.)
If you already work with Simscape Electrical or similar railway toolboxes, mention that in your proposal—the closer this feels to a production-ready drivetrain model, the better.
