On the Design of Close and Open Loop Hexagonal Multiplexer for Communication System

In this paper, close and open loop hexagonal resonator filter, multiplexer of high selectively and compact size are presented. The tri-band multiplexer topology is based on the hexagonal close loop resonators of different size which capacitive coupled from a single input. The filter and multiplexer have been designed on substrate dielectric constant εr = 10.2 and thickness = 0.635 mm. The hexag...

Design a Guidance Law Considering Approximation of Missile Control Loop Dynamics Using Adaptive Back-Stepping Theory

In this paper, a new guidance law is designed to improve the performance of a homing missiles guidance system in terminal phase. For this purpose first of all, the two dimensions equations of motion are formulated, then the approximation dynamic of missile control loop is added to these equations which are nonlinear whit unmatched uncertainty. Then, a new adaptive back-stepping method is develo...

A Close-Loop Conformance Testing System of IEC 61850

—With the development of intelligent substation in China, it becoming more important that the conformance testing of IEC 61850 is used to guarantee the interoperability between intelligent electric devices. In view of the current intelligent substation IEC 61850 conformance testing did not form a closed loop, which led to the lacking of comprehensiveness and integrity, a closed-loop conformanc...

Mechanical System Modelling of Robot Dynamics Using a Mass/Pulley Model

The well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. A new model that was previously proposed by the authors that combines a mass with a pulley (MP) is shown to simulat...
