在TMS320F28379的例程的IDDK_PM_Servo_F2837x-v2中IDDK_PM_Servo_F2837x-Settings.h有
// Define the base quantites
#define BASE_VOLTAGE 236.14 // Base peak phase voltage (volt), Vdc/sqrt(3)
#define BASE_SHUNT_CURRENT 9.95 // Base peak phase current (amp), Max. measurable peak curr.
#define BASE_LEM_CURRENT 12.0 // —– do —–
#define BASE_TORQUE // Base torque (N.m)
#define BASE_FLUX // Base flux linkage (volt.sec/rad)
#define BASE_FREQ 200 // Base electrical frequency (Hz)
BASE_VOLTAGE 236.14定义为逆变器直流母线电压Vdc/sqrt(3),但是程序中却没有用到,是不是在没有开放的代码里定义其为电压的基准值?是否可以改变?
以及
// Variables for Field Oriented Control
// ****************************************************************************
float32 T = 0.001/ISR_FREQUENCY; // Samping period (sec), see parameter.h
_iq VdTesting = _IQ(0.0), // Vd reference (pu)
VqTesting = _IQ(0.13), // Vq reference (pu)
IdRef = _IQ(0.0), // Id reference (pu)
IqRef = _IQ(0.0), // Iq reference (pu)
SpeedRef = _IQ(0.0); // For Closed Loop tests
VdTesting、VqTesting、IdRef、IqRef是标幺值的形式,其基准值是什么?SpeedRef 的单位是什么?
