The effectiveness of vector control depends heavily on the
accurate estimation of rotor flux and speed. Among sensorless techniques, Model
Reference Adaptive System (MRAS) are widely used due to its simplicity and low
computational cost. This chapter presents an advanced vector control strategy
for induction machines that combines a Third-Order Sliding Mode (TOSM) control
scheme with a MRAS–based speed observer. The proposed MRAS-TOSM structure
ensures precise and reliable rotor speed estimation under parameter
uncertainties and varying operating conditions. By integrating third-order
sliding mode control, the system exhibits enhanced robustness against
disturbances and parameter variations (such as stator resistance and rotor
inductance), fast convergence, and minimised estimation errors. Key performance
metrics, including overshoot reduction, settling time, and steady-state
accuracy, are analysed in detail through extensive simulation studies. The
simulation results demonstrate that the proposed approach significantly
improves dynamic performance, stability, and robustness compared to
conventional control methods. The results also highlight its potential for
high-performance industrial drive applications and practical implementations,
making it a suitable solution for both academic research and real-world
engineering systems.
