The theory of management system looks at organization an open system consisting of many subsystems. Being a very important part of firm system, incentive system has direct influences on firm value creation. Interactions of system internal forces and external forces characterize the incentive system nonlinear attributes. This paper analyzes nonlinear relations between incentive inputs and system dynamic...
When regenerative braking electric locomotives are working at the inversion process, there will occur high over-voltage if the failure of regenerative braking happens. It will influence the insulation and the safety of the electric locomotives. According to the magnetization curve and mathematic equation, the dynamic simulation model of SS7 electric locomotives is established. The result shows that...
Identification is considered for the Hammerstein system consisting of a static nonlinear block f(middot) followed by an ARX subsystem, when the system output is observed with noise. No assumption is made on the structure of f(middot). Recursive estimates are given for coefficients of the ARX subsystem and for the value of f(u) at any u. All estimates are convergent to the true values with probability...
Using the drill string to transfer the telemetry data is a focus in the fields of logging while drilling (LWD) and measurement while drilling (MWD). The acoustic property of the drill string is the foundation for improvement the transmission rate. In this paper, we study the filtering property of the drill string using the transfer matrix (TM) method. Compared with the classical finite difference...
The logging-while-drilling (LWD) systems mainly use the mud-pulse telemetry to transmit the measured data from the bottom to the surface. Its transmission rate, however, is very low, which is a severe limitation for the real-time transmission. Recently, using the drill string as the transmission carrier draws people's attentions and becomes one of the research focuses. In this paper, a waveform design...
