In this paper, the output tracking of time-varying linear system is investigated with pseudo division-by-zero phenomenon illustrated. We only use Zhang dynamics (ZD) to design a ZD tracking controller, which is easier than using Zhang-gradient (ZG) method. The purpose of output tracking control for the considered time-varying linear system is to make the actual output track the desired output with...
According to the precision position control requirements of the filter rod splint in the filter rod packing machine system, in this paper, the drive of filter rod plate movement of permanent magnet synchronous motor (PMSM) as the controlled object, on the basis of the mathematical model of PMSM, the three closed loop control system of current loop, speed loop and position loop are determined. In which...
In controlling the robot interacting with the external environment, an important role is played by the force/moment sensors. To design a good force sensor, we need to make a good model first. This paper presents a systematic modeling method of one type of force/moment sensor. A model of a previously designed sensor has been built on the basis of static and kinematic equations and a block form of the...
Online social networks (OSNs) currently face a significant challenge by the existence and continuous creation of fake user accounts (Sybils), which can undermine the quality of social network service by introducing spam and manipulating online rating. Recently, there has been much excitement in the research community over exploiting social network structure to detect Sybils. However, they rely on...
This paper presents an unconventional flat-type linear permanent magnetic generator based energy harvesting system which employs a cascaded boost-buck two-stage converter, with a maximum power control algorithm optimized for low frequency human horizontal foot motion, for Li-Ion battery charging. The dynamic model of the linear generator is built and the analytical equations for maximum power generation...
It is extremely important for airlines to study the flexible seat inventory control issues to prevent flight revenue from spoiled due to inaccurate prediction of air passenger demand. This paper provided a novel capacity control method based on real option and showed how airlines may be considered as the holder of callable tickets. In a fully competitive market, a partial differential equation model...
The design and analysis of a power telemetry system with multiple output voltages is presented in this paper. The system includes a Class E power transmitter, cascaded resonant tank, diode rectifiers, reverse data telemetry and regulators. The power loss associated with voltage conversion is minimized by using a proposed cascaded resonant tank. Reverse telemetry senses the power level fluctuation...
This paper presents a new symbolic methodology for the formal verification of high-level data-flow synthesis process. In the approach, high-level specification of a data-flow design is modeled with Kleene algebra with tests (KAT) as a relational expression. By analyzing this relational expression, assertions that establish properties of the high-level specification are obtained. Then, the problem...
