Following the introduction of knowledge management and its application in process industry CIMS, this paper mainly focuses on the framework of knowledge management for the process industry MES. Based on the study of cost-management situation in a petrol refining corporation, a data flowing process of cost management is set down, and a new function frame of cost management and control concerned with knowledge management is also proposed.

the best measure quantifying FWL (finite word length) stability is the one that bases on the largest stable perturbation hypercube. But the computing of this FWL stability measure has not been solved. For second order digital systems, this paper develops an analytic computing method. through solving 12 linear equations and 12 quadratic equations, the measure value can be obtained exactly.

Water hydraulic servo system is attractive technology for safety environment. this paper deals with water hydraulic servomotor system. To overcome the highly nonlinearity of flow equation, it is linearized and parametrized. Considering the effect of parameter perturbation, e.g. load fluctuation and friction parameters, a method of Lyapunov-based recursive design is applied to construct a robust rotational velocity controller. the effectiveness of the proposed controller is examined numerically.

We investigate the bifurcation behavior of a discrete-time model of Internet congestion control system, which stands for a single link shared by multiple sources. By choosing the gain parameter and the number of sources as bifurcation parameters, we prove the existence of period doubling bifurcation in the model and study the stability of bifurcation. We also find that chaotic behavior of the model can be controlled by limiting the amplitudes of the sending rates.

Ultrasonic motors (USM) possess heavy nonlinear and load dependent characteristics of ultrasonic motors (USM) such as dead-zone and saturation reverse effects, which vary with driving conditions. In this paper, behaviour of an ultrasonic motor is modelled using Hammerstein model structure and experimental measurements. Simulation results show the good matching between the developed model and experimental measurements.
