In order to describe the nonlinear phenomena and to find the regularity of ship rolling motion, the mathematical model of ship nonlinear rolling motion is built. The Lyapunov exponent curve is used to judge the chaos phenomena of ship nonlinear rolling motion. The nonlinear method of the negative feedback control algorithm is employed to control the chaos phenomena and to obtain the appropriate range of the negative feedback coefficient k so that the nonlinear phenomena are mitigated. The results show that the method can achieve a satisfactory control effect. 相似文献

How an articulated mammal learns a foreign language has been a mystery for many years to language researchers. Language scholars have put forward different ways to explain this problem. Yet all of them are not perfect. Each of these theories has contributed both quantitively and qualitively to the different aspects of language learning. However, language learning and teaching doesn't happen in a vaccum. It is affected by many factors. In vast rural areas in China, practically speaking, behaviorist approach fits in with the writer's own experience. Some weaknesses of this approach are also discussed. Therefore what is important is to adapt, not to adopt blindly. 相似文献

In this paper, electrical energy quality and its indices in ship electric networks are introduced, especially the meaning of electrical energy quality terms in voltage and active and reactive power distribution indices. Then methods of measurement of marine electrical energy indices are introduced in details and a microprocessor measurement-diagnosis system with the function of measurement and control is designed. Afterwards, estimation and control of electrical power quality of marine electrical power networks are introduced. And finally, according to the existing method of measurement and control of electrical power quality in ship power networks, the improvement of relative method is proposed. 相似文献
