Fig.7 Performance space of current PR controller parameters 3.2 外环PI控制器参数性能空间 电压外环以稳定输出电压为控制目标,可将输出电压受到扰动后的超调量和调节时间作为其性能空间。传统设计方法中,由于内环带宽远大于外环带宽,为此,当在PLECS软件中建立双闭环控制的离散时域模型时,可认为不同的内环控制器参数...
三相电压型PWM整流器控制系统设计方法的研究_丁奇
Connect to ground to put the controller into the low-power 1µA (max) shutdown state. During startup, the controller ramps up the output voltage at 1/8 the slew rate set by the TIME resistor to the target voltage defined by the application circuit: 11 SHDN For IMVP-6.5 (CLKEN pull...
Could u plz give me some details of making a temperature indicator and controller using LM35,LCD,ADC0804, 89C51 and a fan…plz try to help. i need the circuit diagram and the code for it Alan Parekh said, on April 21st, 2011 at 1:32 am Hi Shija, Sorry, I have never used a 89...
Reference voltage output of the PWM controller. This pin must supply no more than 10 mA under normal operation. This output O is short-circuit protected at roughly 100 mA. This reference is also used for internal comparators and needs a high frequency bypass capacitor of 1 µF. The VCC ...
