Permanent Magnet Synchronous Motor Vector Control Simulation

The Permanent Magnet Synchronous Motor (PMSM), known for its high efficiency and superior performance, is widely used in industrial drives, electric vehicles, and servo systems. Field-Oriented Control (FOC) serves as a core control strategy for PMSM, achieving independent control of torque and magnetic field by decomposing three-phase currents into direct-axis (d-axis) and quadrature-axis (q-axis) components through Clarke and Park transformations. This approach enhances system dynamic response and overall efficiency.

During simulation, it's essential to build a comprehensive control model that includes coordinate transformation modules (Clarke-Park transformations), PI regulators for current and speed loops, and Space Vector Pulse Width Modulation (SVPWM) algorithms. The debugging process focuses on analyzing current loop dynamic response, speed tracking performance, and optimizing control parameters using systematic tuning methods to ensure stable system operation.

Simulation allows for validation of control algorithm correctness, optimization of parameter adjustments through iterative testing, and reduction of real hardware debugging challenges. The ultimate objective is to achieve high-precision, high-efficiency motor drives, providing reliable solutions for practical engineering applications through robust control system implementation.
