The invention relates to the technical field of automatic control, particularly to an automatic door control method and system based on a permanent magnet synchronous linear motor. According to the invention, a vector control permanent magnet synchronous linear motor replaces a traditional direct-current brushless or brush motor to drive and control an automatic door, so that the operation safetyof the automatic door is remarkably improved, the structure is simplified, and installation and maintenance are convenient; a Hall sensor is used for replacing a traditional permanent magnet synchronous linear motor position acquisition sensor, so that the detection cost is reduced; the subsequent torque of the permanent magnet synchronous linear motor is linearly corrected according to the position detection result of the Hall sensor, so that the torque pulsation of the motor can be reduced, and the running noise of the automatic door is effectively reduced; the permanent magnet synchronous linear motor is used for carrying out deceleration brake control on the automatic door, wherein the speed-time relation is an S-shaped curve; and the stable acceleration and deceleration performances can be obtained, so that the driving control process of the automatic door becomes smooth, and the mechanical impact is reduced.
