Boost_Converter
说明: 升压转换器是一种DC / DC电源转换器,可将电压从其输入(源)升至其输出(负载)。在连续导通模式下(流经电感的电流永远不会降为零),升压转换器的理论传递函数为:
占空比在哪里0.5
在此示例中,转换器从250 V电源馈送RC负载,并且PWM频率设置为31 kHz。
模拟
运行仿真并观察示波器上的波形。确认负载电压(Vout)的平均值非常接近理论值:Vout = 250 /(1- 0.5)= 500V。(A boost converter is a DC/DC power converter which steps up voltage from its input (source) to its output (load). In continuous conduction mode (current through the inductor never falls to zero), the theoretical transfer function of the boost converter is:
where is the duty cycle.0.5
In this example, the converter is feeding an RC load from a 250 V source and the PWM frequency is set to 31 kHz.
Simulation
Run the simulation and observe waveforms on Scope. Verify that the mean value of the load voltage (Vout) is very close to the theoretical value of: Vout = 250 / (1 - 0.5) = 500 V.)

数字控制系统是一种以数字计算机为控制器去控制具有连续工作状态的被控对象的闭环控制系统。因此,数字控制系统包括工作于离散状态下的数字计算机和工作于连续状态下的被控对象两大部分。我的课题的数字部分(PID)仿真由相应的离散传函实现,运用数字PID对被控对象实行准确控制。通过调节比例(P)、积分(I)、微分(D),使对象的输出达到预期的效果。(Digital control system is a kind of digital computer for the controller to control a continuous state of the object and closed loop control system. Therefore, the digital control system, including work on the discrete state of the digital computer and work in a continuous state of the plant is two parts. My topic of digital section (PID) simulation by the realization of the corresponding discrete transfer function using the digital PID control of the plant is implemented accurately. By adjusting the ratio of (P), integral (I), differential (D), so that the output of the object to achieve the desired results.)
