Abstract: This work deals with the performance and optimisation of the speed control of a doubly fed asynchronous machine (DFIM), modelled considering the magnetic circuit’s saturation. The speed control strategy of the machine, thus implemented, is the super twisting with integral action, consisting of 5 regulators, including 4 for stator and rotor currents and 1 for speed regulation. The control was done without a mechanical sensor thanks to an observer which reconstructs the rotation speed of the machine from the reading of the currents and voltages absorbed by it. The coefficients of the regulators and those of the observer were determined by the Particle Swarm Optimisation (PSO) methods. Thus, the system’s efficiency was tested and validated on several speed ranges, i.e., very low speeds, low speeds and high speeds in the MATLAB/Simulink simulation software. The control system’s performance was demonstrated by varying the set speed according to a predefined profile. The resistive torque and the rotor and stator resistances values were modified by up to 50% to demonstrate the insensitivity to disturbances or variations in the machine parameters.
