A new adaptive high speed control algorithm used for a FOC or a DTC PMSM drive strategies

This paper presents a new adaptive high speed control algorithm (AHSC) for the permanent magnet synchronous motor (PMSM) drives. This AHSC algorithm has been built by using the Model Reference Adaptive System (MRAS) and with reference to the fed inverter variables limitation. The proposal control technique is mathematically formulated and implemented in the two conventional motor control strategies such as the Field Oriented Control (FOC) in one hand and the Direct Torque Control (DTC) on the other hand. The proposed AHSC is tested through computer simulation using MATLAB/Simulink, where the system efficiency and robustness is verified for a wide speed range and under the two cited drive strategies. The obtained simulations results are satisfactory and confirmed the usefulness of the overall proposed control algorithm.
