Five-Phase Induction Motor Speed and Torque Control with Fractional-Order Sliding Mode Control (FOSMC) in MATLAB Simulink

Research objective

Investigate fractional-order sliding-mode speed regulation for a five-phase induction motor, with particular attention to transient speed tracking and electromagnetic torque ripple.

Software and model scope

Primary environment: MATLAB/Simulink. Discipline: Electrical Machines and Drives. The video provides a project demonstration; source models, solver settings and plots should be checked against the actual implementation before reuse.

Simulation / modelling methodology

• Represent the five-phase motor electrical variables and the applicable multi-axis transformation or equivalent state-space model.
• Design a speed reference loop and a fractional-order sliding surface with explicit order, gain and approximation method.
• Connect the controller to a suitable five-leg inverter or voltage synthesis stage with current and modulation limits.
• Run startup, reference-speed steps and load-torque disturbance tests against a fair baseline controller.

Outputs and checks for validation

• Rotor speed reference, actual speed and tracking error
• Electromagnetic torque waveform and ripple index
• Five stator-phase currents and inverter reference voltages
• Sliding variable, control effort and load-disturbance response

How to interpret results

Reduced oscillation must be assessed alongside speed settling, current stress and actuator saturation. Numerical fractional-order approximations can influence chattering and comparison fairness.

Verification caveat: Check five-phase winding order and 72-degree electrical displacement; document fractional-operator approximation, sample rate, motor parameters and initialization.

Applications for OEM and PhD research

Fault-tolerant multiphase traction drives, high-reliability propulsion and advanced nonlinear motor control research.

Frequently asked questions

Which software is used for this simulation?

MATLAB/Simulink is the primary environment named in this project.

What should be checked before using its results?

Check five-phase winding order and 72-degree electrical displacement; document fractional-operator approximation, sample rate, motor parameters and initialization.

Can this project support a new research comparison?

It can serve as a reference workflow, but any new claim requires a fresh model, documented parameters, independent validation and genuinely measured outputs.
