vfmrasti.h

本程序来自TI公司网站原程序,其功能是通过传统的V/F控制算法并加上对电机的转子速度辨识即无速度传感器控制来实现对感应电机的控制,控制程序可以采用.asm也可以采用.C。程序的具体算法和介绍在软件压缩

/* ==============================================================================
System Name:  ACI3_2

File Name:	VFMRASTI.H

Description:  Header file for Peripheral independent object for implementation 
              of Sensorless Volt/Hertz control of a Three Phase AC Induction 
              Motor using reactive power MRAS speed estimator.

Originator:		Digital control systems Group - Texas Instruments

Target dependency:	x240/1/2/3/07 
To Select the target device see target.h file.

Note that the PWM/sampling frequency in C system is running at 15 kHz, which 
is different from the PWM/samping frequency in ASM system (i.e., 20 kHz) as 
indicated in the ACI3-2 system documentation. Also, this PWM/samping frequency
in both ASM and C systems are based on x2407 with 40 MHz clock. If the x243 with
20 MHz clock is used, then the PWM/samping frequency may be decreased accordingly.
