Permanent Magnet Synchronous Motors (PMSM) are extensively used in the industry owing to their excellent efficiency, low weight/power ratio, and smooth torque with no or minimal ripple. Field Oriented Control (FOC) is a modern and effective approach for closed-loop controlling the speed of PMSM. In this paper, three-level Space Vector Pulse Width Modulation (SVPWM) is proposed for minimizing harmonics in the output voltage inverter. sensorless approaches are performed by using Model Reference Adaptive System (MRAS) which eliminates mechanical uncertainties. Because mechanical sensors increase the cost, size, weight, and wiring complexity, employing PMSM with them is extremely difficult Tuning of Proportional Integral (PI) controller gains is performed by using the Whale Optimization Algorithm (WOA). The results show that the proposed controller enhances the system's performance. In the application of felid-oriented control to a PMSM, with simulation data to back it up the entire system is simulated using the MATLAB/Simulink tool.
