| 9. | Some research about sensorless control of induction motors in recent years has been introduced in chapter one . in chapter two , a field - oriented control system with current regulator and voltage source inverter ( vsi ) is presented firstly , which is proved in theory that the voltage feed - forward decoupler can be omitted , the good decoupled control properties of flux current and torque current is also validated by experiments with speed - sensor based on f240dsp real system
论文第二章从异步电机的基本数学模型入手，介绍了一种基于转子磁场定向的带电流内环控制的电压型逆变器输出闭环矢量控制结构，在理论上证明了该模型可省略电压前馈解耦环节，采用f240dsp芯片构建的带速度传感器实验系统验证了其定子电流励磁分量和转矩分量有良好的解耦控制特性。 |
| 10. | The feedback of the output voltage is the major control loop . to achieve better frequency response and disturbance rejection of the input voltage , a input voltage feed - forward system is introduced in control loop . the duty - cycle of pwm applied at the gate of power mosfet is modulated by both input and output voltage
该芯片采用的控制方式为电压型pwm (脉冲宽度调制, pulsewidthmodulation )控制方式,以输出电压反馈作为主要控制参量,同时为了提高芯片对输入电压扰动的响应速度,采用了输入电压前馈方法,将输入电压因素引入了反馈控制环中,通过对输入输出电压的检测,控制加在功率mos管栅极电压上矩形脉冲的占空比,进而调节输出电压。 |
