GMCLIB
Description
Removes cross-coupling from PMSM control signals and compensates the BackEMF voltage. Both operations are done in d-q frame according to the following equations:
Parameters and dialog box
The block dialog box appears as follows:
Ld - direct axis inductance [H]
Lq - quadrature axis inductance [H]
Psi - BackEMF constant [V.sec/rad]
Inputs and outputs
Inputs:
u_d - direct axis voltage [V]
u_q - quadrature axis voltage [V]
i_d - direct axis current [A]
i_q - quadrature axis current [A]
w_e - electrical speed [rad/s]
Outputs:
u_d_dec - decoupled direct axis voltage [V]
u_q_dec - decoupled quadrature axis voltage [V]
