The hybrid Internal Model Control and Proportional Control learning scheme are introduced. In order to gain the desired robust performance and ensure the system's stability, Adaptive Momentum Algorithms are also developed. Through properly designing the neural network plant model and neural network controller, the chaotic dynamical systems are controlled while the parameters of the BP neural network are modified. Taking the Lorenz chaotic system as example, the results show that chaotic dynamical systems can be stabilized at the desired orbits by this control strategy.展开更多

Especially under the background of China＇ s rapid integration into the global economy, the rapid establishment and improvement of the context of the modem enterprise system, the issue is of utmost importance. The internal accounting control system is the core part of internal control, which determines the extent of establishing the entire sound internal control system, With the progress of the time, the rapid development and wide application of Internet technology has changed the survival environment and management philosophy for business. The development of network technology achieves the online office, mobile office and decentralized offices, etc. Accounting entity is no longer subject to space limitations of traditional methods, thus a large number of accounting information is transmitted tbaough the network communication lines, so that accounting activities can be extended to every node in the world, which achieves the purpose of remote processing. Under the network environment, sources of information are of diversity and multi-channel. A large number of accounting information transmitted from the network communication lines is likely to be illegally intercepted, stolen and tampered by molecules or people with ulterior motives.展开更多
