Embodiment Construction
[0116] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0117] combine figure 1 As shown, the command filtering finite time fuzzy control method of permanent magnet synchronous motor mainly includes the command filtering fuzzy finite time controller 1 of permanent magnet synchronous motor, coordinate transformation unit 2, SVPWM inverter 3 and speed detection unit 4 with current sense unit 5. in:
[0118] The speed detection unit 4 and the current detection unit 5 are mainly used to detect the current value and speed-related variables of the permanent magnet synchronous motor. The actual measured current and speed variables are used as input, and the permanent magnet synchronous motor drive system based on command filtering fuzzy finite time The controller 1 performs voltage control, and finally converts to three-phase electricity to control the speed of the permanent magnet synchronous motor. In ...
