Control system and method of permanent magnet synchronous motor

The invention discloses a control system and method of a permanent magnet synchronous motor, relates to the technical field of motor control, and is used for solving the problem that the convenience and operability of an existing control system of the permanent magnet synchronous motor in practical application have certain limitations, and the control system comprises a sensing module, a man-machine interaction module, an analysis module and an execution module; the sensing module is used for sensing the operation state of the permanent magnet synchronous motor through different sensors, and the operation state specifically comprises the rotation direction, real-time torque data, power factor data, rotation speed data and acceleration or deceleration data of the permanent magnet synchronous motor. According to the invention, more intuitive and convenient control of the permanent magnet synchronous motor is provided for a user through a relatively simple man-machine interaction interface, so that non-professio
