| Summary: | Based on the vector control of the surface-mounted permanent magnet synchronous motor( SPMSM) ，the leading angle flux magnetic weakening control is realized and the speed adjustment range is expanded． On this basis，the first order limited-amplitude low pass filter is used to filter the traditional leading angle flux magnetic weakening control to eliminate the buffeting phenomenon of the motor． In this paper，the stator voltage phase value is taken as the input quantity． After calculation and filtering，the d and q axis migration angles are fed back to the current ring as the output quantity，so as to realize to expend the speed adjustment range． Simulation and experiment prove that the leading angle flux weakening control can expand the speed range of the motor and run smoothly，achieving the purpose of speed expansion． |
