The access control of military information systems (MIS) is an important issue that imposes significant influence on the MIS security. First of all, we did in-depth analysis of the main factors of access control model, such as the basic principle and constraints of models, the formal definition of model components, and the permissions and inheritance of models. Furthermore, the idea of security domain management and control is introduced in this chapter and based on existing access control model, SDO-ARBAC (Security Domain-Oriented-Administrative Role-Based control Model) is built which is more suitable for MIS access control.

This article conducts a research on wheel slip ratio control for distributed drive electric vehicles. In consideration of wheel rotation dynamics and its strong nonlinear properties, a proportional-integral controller is designed in this paper aimed at regulating the wheel slip ratio to a constant value regardless of the road adhesion conditions. At the same time, an online road coefficient estimator is proposed to provide optimal slip ratio for the designed wheel slip ratio controller. The global asymptotic stability of the system is proved by the Lyapunov stability theory. In addition, a distributed drive electric vehicle model is established for performance assessment due to its precise and fast-response torque control. Simulation results show that the proposed controller adaptively regulates the wheel slip ratio to the optimal value of current road with fast convergence speed and high accuracy. Generally, the proposed adaptive controller greatly improves the driving performance of the electric vehicle.
