Predictive Torque Control of PMSM with speed fuzzy logic controller

Permanent magnet synchronous motors (PMSM) are extensively used in aerospace and electric vehicles. Earlier, Field Oriented control (FOC) is very frequently used in the speed control of PMSM drives gives excellent steady state characteristics. Nonetheless, FOC has three PI controllers, tuning of which is heavy burden on the processor. Although, Model predictive control (MPC) techniques are used to eliminate two PI controllers, still one speed PI tuning is necessary in conventional Predictive Torque Control (C-PTC). In this paper, a fuzzy logic controller (FLC) is designed using mamdani fuzzy inference system (FIS) to eliminate the speed PI controller in conventional PTC. The proposed PTC method gives better steady state responses, eliminates the overshoot in dynamic response and reduces the switching frequency of the inverter. The effectiveness of proposed PTC is verified in MATLAB/SIMULINK environment and the results are presented.
