Based on the unification of the Chinese traditional culture and the “YIN and YANG” principles, it discusses how to understand the hypotheses of the organizational models, analyzes the traditional and the leading models, and puts forward two hypotheses, the fixed structure and the flexible structure of organizations.展开更多

To illustrate the type of results which can be obtained using the new optimized decentralized control design method, the control of a large flexible space structure is studied and compared with the standard centralized LQR-observer controller. The order of the resultant decentralized controller is much smaller than that of the standard centralized LQR-observer controller. The proposed controller also has certain fail-safe properties and, in addition, it can be five orders of magnitude more robust than the standard LQR-observer controller based on their real stability radii. The new decentralized controller design method is applied to a large flexible space structure system with 5 inputs and 5 outputs and of order 24.展开更多
