The objective of this study is to investigate a three-phase induction motor (IM) based photovoltaic solar water pumping system (PVWPS) that has cheap cost, good performance, and doesn't require chemical energy storage. There are two main controllers in the PVWPS control scheme. The first controller uses a strong MPPT control strategy based on the Kalman filter algorithm (KF-MPPT) to regulate the system to attain its maximum. Conversely, the second controller uses Direct Torque Control (DTC) with a 12-second timer. This method involves using a three-level inverter with a neutral point clamped (NPC) arrangement to regulate the IM using a centrifugal pump. Additionally, by raising the torque and flux hysteresis regulator levels to three and five levels, respectively, the suggested control's performance is improved without compromising the efficiency of the system. The entire system was constructed and simulated in the MATLAB/Simulink environment to observe the behaviors of the PVWPS with the suggested control. A comparison study is also included in this paper to demonstrate how well the suggested control performs in contrast to the traditional controls. Using varying radiation, the performance of the KF-MPPT, VSS-P&O-MPPT, and VSS-INC-MPPT is first compared. Next, the suggested KF-MPPT-PDTC and the traditional KF-MPPT-DTC are compared under a daily climatic profile.
