作为一个系统来讲,电动机和运动控制器不仅仅是一系列元器件的总和。Faulhaber公司就用自己的产品展示了只有使用合适的运动控制器才能可靠地驱动小型电动机实现自动化。在自动化控制领域中,机械设备的运动通常都要精确地、动态地和灵活地予以控制。例如,没有人愿意让不安全的机器人给自己做微创手术。即便是在CNC数控机床加工过程中数控机床的刀具和材料供给也都必须做到非常精确,只有这样才能确保零件的加工精度。但如果没有合适的驱动装置就无法完成此类任务。

Journal of Modern Power Systems and Clean Energy 2022年第5期10卷 1216-1228页

Accurate short-term load forecasting is essential to modern power systems and smart grids. The utility can better implement demand-side management and operate power system stably with a reliable load forecasting system. The load demand contains a variety of different load components, and different loads operate with different frequencies. The conventional load forecasting methods, e.g., linear regression(LR), auto-regressive integrated moving average(ARIMA), deep neural network, ignore the frequency domain and can only use time-domain load demand as inputs. To make full use of both time-domain and frequency-domain features of the load demand, a load forecasting method based on hybrid empirical wavelet transform(EWT) and deep neural network is proposed in this paper. The proposed method first filters noises via wavelet-based denoising technique, and then decomposes the original load demand into several sub-layers to show the frequency features while the time-domain information is preserved as well. Then, a bidirectional long short-term memory(LSTM) method is trained for each sub-layer independently. In order to better tune the hyperparameters, a Bayesian hyperparameter optimization(BHO) algorithm is adopted in this paper. Three case studies are designed to evaluate the performance of the proposed *** the results, it is found that the proposed method improves the prediction accuracy compared with other load forecasting method.
