This paper investigates the sliding mode control of three-phase voltage source PWM rectifier (VSR). When the three-phase VSR system is applied in different environmental conditions, external disturbances are inevitable and stochastic, so these conditions should be taken into consideration when designing the controllers. To have a good performance and a fast response, the whole closed loop control...
Precise load measurement is important for the supervision of the pulverizing process in thermal power plant. This paper presents an adaptive soft sensor based on PCA and FasArt neural networks to achieve this purpose. PCA is firstly used to compress the input secondary variables and the dimension is reduced from 9 to 3 with little loss of information. Then FasArt model derive the knowledge from the...
Precise load measurement is important and difficult for an industrial scale ball mill in thermal power plant. This paper presents a new approach which combines a novel feature extraction method and a hierarchical model to achieve this purpose. By analyzing the sensitivity distributions of working condition transitions and removing the ineffective information, the characteristic power spectrums (CPS)...
