Hi Team,
Here're some issues from the customer may need your help:
With TI TMS320F28335, I am trying to use Sliding-Mode Rotor Position Observer of PMSM provided by TI.
I am using the modules of "smopos_const.h" and "smopos.h".
I have some questions, could you please help me?
1.
TI provides sliding-mode rotor position observer for PMSM. Can I used it for both of SPMSM and IPMSM? Or it is just for SPMSM?
2.
When using TI SMOPOS, the paramters of Ib and Vb are needed to configure. How to configure them?
Regarding to Ib, is it RMS value? And is it the maximum motor current?
Regarding to Vb, the voltage is different at different speed, how much it needs to be configured? Thank you very much.
typedef struct {
float32 Rs; // Input: Stator resistance (ohm)
float32 Ls; // Input: Stator inductance (H)
float32 Ib; // Input: Base phase current (amp)
float32 Vb; // Input: Base phase voltage (volt)
float32 Ts; // Input: Sampling period in sec
float32 Fsmopos; // Output: constant using in observed current calculation
float32 Gsmopos; // Output: constant using in observed current calculation
} SMOPOS_CONST;
