Based on the enlarged system with integral action,the optimal sliding mode variable structure controller was designed for the actuator load system by constructing the sliding surface with quadratic optimization and adopting the reaching law with good dynamic character,considering the uncertainty of unmodeled part,parameter time-v.

How to Determine the Optimal Structure of China's Expenditure on National Defense——An Empirical Study on the Distribution Proportion of Project Expenditure

On the base of the principle of determination redundancy, this paper derives the basic condition for the design of the optimal redundant structure for the Flight-control/Inertial integrated system MIRAstructure matrix should be all rank; further discusses the design of the optimal structure for structure matrix.

In this paper we study the diversification which is one of the methods decreasing economic risk, point out that the hypertheses used by traditional portfolio theory are not always true, and propose several mathematical models to explain the optimal structure of portfolio.
