Nowadays configuration parameters about network and service in intelligent terminals are getting more complex. Faults and security risks in the terminal are increasing. These have become key holdbacks for usage of services. So it is necessary to manage the terminals to keep them normal and promote satisfaction from customer. OMA and 3GPP have done researches about management of terminals. But there...
This paper presents a generic self-aware solution to guarantee the security of PTN network on ECMP condition. This mechanism, called OAM detection and multipath switching (ODMS) has two points. The first one is sending specific OAM packets periodical to detect out of order status of data flow. The second is switching the routing paths in variable periods according to the flowpsilas out of order proportion...
In this paper, an uniform mathematic model of three-level inverters feed induction motor drives system has been constructed. Based on the application of the discrete space vector modulation (DSVM), a DTC strategy of three-level inverters induction motor drives system is proposed. With DSVM-DTC algorithm, the neutral-point (NP) voltage balancing problem and high dv/dt of output voltage is restrained...
The mathematical model of the three-level PWM rectifiers is set up in this paper. By comparing it with the model of DC motors, some similarities are established. Based on the state feedback decoupling, the dual-loop close control scheme of DC motors is implemented to three-level PWM rectifiers. As a result, the three-level rectifier has favorable dynamic and steady state performance, sinusoidal input...
