周期性负荷 meaning in English

periodic duty

As the ratio of peak samples to total training samples is low , the prediction accuracy of peak load is poor when applying support vector machine ( svm ) model to predict a periodical load
在应用svm模型于具有周期性负荷的预测时，由于在训练样本中峰值或谷值样本所占比例很少，从而导致峰值荷载预测精度不高。
The states of the system and their differential signals are obtained on time by tracking differentiator , and the influence induced by nonlinear periodic load disturbance is compensated adaptively
电力系统混沌振荡状态和它的微分信号由微分跟随器实时提取，并通过微分跟随器对非线性周期性负荷扰动的影响进行自适应补偿。
