[Software Engineering] PC-Fan-Control-using-ATtiny13 DL : 0: PC Fan Control using ATtiny13... This application note describes the operation of 12 volt DC cooling fans typically used to supply cooling air to electronic equipment: These fans are typically based on two-phase Brushless DC (BLDC) motors drawing between 1 and 50 watts of power. Single-phase brushless DC motors are also used in fans, but this is outside the scope of this application note. Further discussion describes the addition of an Atmel ATtiny13 microcontroller and the benefits this offers, such as variable speed by external thermistor input. An additional input is a PWM pulse width-varying signal, which also controls fan speed.

[Software Engineering] dsPIC30F_ACIM DL : 0: 压频比控制方法非常适用于风机和泵等负载变化较慢的应用场合。但对于需要快速动态响应的应用场合则效果不佳。特别是在速度或转矩发生快速变化时，由于较高的转差率则会导致较大的瞬态电流。如果同时对电机转矩和磁通进行闭环控制，则可以在不产生大电流的条件下实现快速的动态响应。矢量控制技术可以实现上述目标，通常也被称作磁场定向控制（FOC）。-Voltage to frequency ratio control method is very suitable for fan and pump applications where the load changes slowly. But the need for applications where fast dynamic response is ineffective. Especially in the speed or torque changes occur rapidly, due to higher slip will result in a larger transient current. If both the motor torque and flux for closed-loop control, you can not produce high current conditions to achieve fast dynamic response. Vector control technology can achieve these goals, also commonly referred to as field-oriented control (FOC).
