Some scholars put forward the concept of manager cognizance that is a group of fixed rule system and believe that new rule system will replace old one and old rule system will be forgotten when the environment changes . the explanation affect the dynamic mechanism study on manager adaptability . the concept of “ adaptive main body ” in holland ’ s complex adaptive system theory accords with the understanding of enterprise in this paper 尽管有学者提出管理者认知的概念,将管理者认知描述成一组固定的规则系统,认为当环境改变时新的规则系统将完全取代旧的规则系统,并将旧的规则系统全部忘记,这种对认知概念的机械式解释影响了对管理者适应性的动态机制研究。
Apf control realization can be either digital or analogical . the advantage of digital compensating control ( dcc ) is that it can compensate harmonics to a precision level and is independent of the surrounding environment . but dcc needs high - speed real - time chips to deal with digital signal processing , so has high price ; analog compensating control ( acc ) demands hardware very rigidly 数字补偿控制的优点是可以对电网谐波的补偿达到很精确的程度，不容易受运行环境改变的影响，但是要求运算速度很高的实时数字信号处理芯片，因此造价较高；模拟补偿控制对硬件的要求比较严格。
