专利汇可以提供Plant optimizing control device专利检索,专利查询,专利分析的服务。并且A plant optimizing control device in which a slight variation is caused in the input by applying a search signal to the input and the preset value of the input is adjusted on the basis of an optimizing signal so as to cause the operating point of the plant to give an optimum point by measuring the variation in the output corresponding to the variation in the input, the device comprising a first means for generating a periodical signal consisting of pseudo-random binary signals and serving as the search signal, a second means for obtaining a correlating signal with respect to the input and output of the plant, from a running mean within a period of the signal of the first means, the running mean being made in accordance with the expected plant characteristic; a third means for detecting the output of the plant, estimating from the detected value a dc component corresponding to the optimizing signal and obtaining a signal corresponding to the search signal which is equivalent to the detected value minus the dc component; a fourth means for obtaining from the outputs of the second and the third means the gradient of the variation in the output of the plant; and a fifth means for obtaining the optimizing signal of the plant from the fourth means.,下面是Plant optimizing control device专利的具体信息内容。
