交流电动机的矢量控制(Transvector Contrl)理论,从理论上解决了交流电动机转矩的高性能控制问题。其基本思想是在普通的三相交流电动机上设法模拟直流电动机转矩控制的规律,在磁场定向坐标上,将电流矢量分解成产生磁通的励磁电流分量 和产生转矩的转矩电流分量 ,并使两分量互相垂直,彼此独立,然后分别进行调节。这样,交流电动机的转矩控制,从原理和特性上就与直流电动机相似了。因此,矢量控制的关键仍是对电流矢量的幅值和空间位置的控制。(AC motor vector control (Transvector Contrl) theory, control theory to solve the problem of high-performance AC motor torque. The basic idea is to try to simulate the DC motor torque control law in the ordinary three-phase AC electric motor in field-oriented coordinates, the current vector decomposed to produce the excitation current component of the magnetic flux generating a torque current component and torque, and two components perpendicular to each other, independently of each other, and then were adjusted. Thus, AC motor torque control, the principle and characteristics of the DC motor on and similar. Therefore, the key vector control is still the amplitude and spatial position of the current vector control.)

CC1101Schematic-experimental-code
MSP430g2553实现CC1101无线通讯。
最近有个项目,使用CC1101无线传输控制,刚开始做使用MEGA8实现,当晚也没有考虑功耗的问题,但最后项目要求用电池供电,这就出现问题了。无线在发射时的系统的整个功耗在16ma左右,这样一算,不论实用什么电池也不能实现一个月的工作时间。但是要实现,就要一步一步的调试。第一部做的是把MEGA8的供电降到3.3V, 这样的系统的功耗能够降低一半,但是总的时间还是不能实现;第二部把系统的DC/DC稳压片替换成低电流输出、低功耗的稳压电源。这样两步下来,系统功耗降到8ma,可惜的还是不能实现。再进一步,让无线间隔性工作,工作30S,停30S。这样功耗又进一步下降,但是用电池供电的话,只能维持10天左右,要想实现30天,不太可能啊。
CC1101原理图实验代码
拿到LaunchPad后,第一想到是将代码移植到上面,看看系统的功耗。今天上午很容易移植成功了,一没功耗,让我看到了希望,在没有采取任何降低功耗的措施下,系统的功耗是4ma,无线一直在工作状态。太好,如果采取功耗设计,我想一定能够实现项目要求,期待能够调试出更低的功耗。
