摘要

本文提出了一种SEPIC变换器的PI(比例积分)和SMC(滑模控制)方法。该方法的优点是不需要PWM调制器，只使用两个PI增益。利用Routh-Hurwitz稳定性准则和广义根轨迹计算PI增益。为了进行比较，在加入PI和SMC之前，首先采用迟滞法控制变换器，然后采用四阶和二阶滑模控制。得到了SMC的系数。利用MATLAB实现了SEPIC的PI和SMC控制，并给出了控制结果。

Four controls of Sliding Mode Control of a SEPIC converter

This paper presents a PI (Proportional-Integral) and SMC (Sliding Mode Control) of a SEPIC converter. The advantage of this method is that it does not need a PWM modulator and only two PI gains are used. The PI gains are calculated through Routh-Hurwitz stability criterion and generalized root loci. To make a comparison, initially the converter is controlled by hysteresis method and subsequently with a fourth and second order Sliding Mode Control before incorporating PI and SMC. The coefficients for SMC have been obtained. The PI and SMC control for SEPIC is then implemented using MATLAB and the results are presented.
