  • The origin and evolvement of cuk converter are introduced and the voltage and current waveforms of every period are analyzed and presented . the state differential equations of ideal cuk converter are deduced and the simulation models of ideal cuk converter , ac power supply and pulse width modulator ( pwm ) are erected
    论文介绍了cuk型dc / dc变换器由来、演变;分析了各个环节、期间的电压、电流的变化情况及波形;推导了理想cuk变换器的状态方程;建立了cuk主电路以及相关交流电源、脉冲宽度调制器的simulink仿真模型。
  • In the positioning servo - system , which generally is configured by the d . c . pulse width modulator ( pwm ) velocity governing system and position servo - loop , the parameter perturbance of pwm velocity loop really exist by reason of such as the load behavior ; power voltage supply ; operating setting value , etc . 1 , 2 , and it cannot be ignored . by using the identification technique to form the mathematical model of the system , authors have confirmed the facts . therefore , to design the discrete sliding mode controller ( dsmc ) of the positioning servo - system , the perturbed parameters value bounds of the pwm velocity loop , which is as the controlled plant of position servo - loop , should be accounted . consequently , the design principle of dsmc for accounting system with parameter perturbance is proposed by the authors . the proposed method can ensure the stability of system with parameter perturbance and the behavior of non - overshoot , fast precise positioning . in order to reveal the effects of the design method , the comparative research work is done by the authors . also , it has been tested in an industrial experiment , the results proved it is satisfactory
    由直流脉宽调速系统( pwm )和位置环构成的定位系统中,速度环的参数随负载特性;电网电压;给定工况而摄动是不容忽视的.作者通过系统辨识建模也证实了这一事实1 , 2 .因此在设计位置环的离散滑模控制时,必须针对速度环(即位置环的控制对象)的参数摄动范围采用“对象参数摄动离散滑模控制器的设计方法” ,以确保系统在参数摄动时的稳定性和快速、无超调、准确定位的优良动态品质.为剖析该设计方法的控制效果,本文作了对比性研究,并将该设计方法用于工业试验中,取得了满意的结果
