Clarke
Synopsis
Curr_Components Clarke (Curr_Components Curr_Input)
Description
This function transforms stator currents ias and ibs (which are
directed along axes each displaced by 120 degrees) into currents iα
and iβ in a stationary (α β) reference frame; αβ axes are directed
along paths orthogonal to each other.
See Section 5.4.2 for the details.
Input
Stator currents ias and ibs (in q1.15 format) as members of the
variable Curr_Input, which is a structure of type Curr_Components.
Returns
Stator currents iα and iβ (in q1.15 format) as members of a structure
of type Curr_Components.
Functions called
mul_q15_q15_q31
Park
Synopsis
Curr_Components Park (Curr_Components Curr_Input, s16 Theta)
Description
The purpose of this function is to transform stator currents iα and iβ,
which belong to a stationary (α β) reference frame, to a reference
frame synchronous with the rotor and properly oriented, so as to
obtain iqs and ids.
See Section 5.4.2 for details.
Input
Stator currents iα and iβ (in q1.15 format) as members of the variable
Curr_Input, which is a structure of type Curr_Components; rotor
angle θ r el (65536 pulses per revolution).
Returns
Stator currents iqs and ids (in q1.15 format) as members of a
structure of type Curr_Components.
Functions called
mul_q15_q15_q31, Trig_Functions
Rev_Park
Synopsis
Volt_Components Rev_Park (Volt_Components Volt_Input)
Description
This function transforms stator voltage vq and vd, belonging to a
rotating frame synchronous with the rotor, to a stationary reference
frame, so as to obtain vα and vβ.
See Section 5.4.2 for details.
72/121
Input
Stator voltages vqs and vds (in q1.15 format) as members of the
variable Volt_Input, which is a structure of type Volt_Components.
Returns
Stator voltages vα and vβ (in q1.15 format) as members of a
structure of type Volt_Components.
Functions called
mul_q15_q15_q31
