Part Number: TMS320F28335
Other Parts Discussed in Thread: CONTROLSUITE
I am trying to use TMS320F28335 chip to drive permanent magnet synchronous motor. I use the ECAP module of TMS320F28335 chip to capture the rotor position of the motor, and use the open-loop FOC control algorithm to calculate the PWM signal of the driving motor. However, the current phenomenon is that with the increase of the motor speed, the motor jitter is more obvious. What is the cause of this? In other words, when using the TMS320F28335 chip to drive the motor, what are the causes of motor jitter? Thanks for your answer
