High-Performance and Robust Field-Oriented Control of IPMSM Drive Over Wide Speed Operation by PI and Fuzzy Intelligent Controllers

Objectives: This paper simulates a high-performance PI and FLC-based controller for an IPMSM drive in which the speed should closely follow reference voltage-current trajectory with different conditions like load disturbance, variation circuit parameters, control strategy. In FOC, fuzzy are used sliding mode control. generates d-axis current (Id) q-axis (Iq), torque magnetic field vector each stator winding, so of motor can be effectively controlled. Methods: this paper, we two loops: one is outer loop, another inner loop called pulses inverter. The optimal behavior controllers designed based on Maximum Torque per Ampere (MTPA) method stand-still to base operation Field Weakening (FW) above operation. mathematical model derived from its dynamic d-q model. proposed system simulated MATLAB-Simulink software speeds loads. Moreover, fixed-gain mostly affected by step change speed, condition. accurate becomes complex issue due non-linear coupling between rotor nonlinearity torque. Therefore, more popular highperformance drives. Novelty: FLC as controller, scheme reduces computation real-time implementation. hysteresis used, outputs given logic, switch ON OFF robustness verified theoretical simulation results. three inputs are: wr Δe error. Fuzzy rules developed membership functions obtain optimized value (Id * Iq*), gives precise under operatingconditions over wide range.
