Abstract The support of renewable energy to the bus voltage during grid fault period will cause failure action backup automatic switch (BPAS). Moreover, improper coordination and source supply lines in process BPAS operation lead asynchronous close a circuit breaker, which seriously threatens stable power system. To solve above problems, an optimal strategy applied remote is proposed this paper...

Manual work is taken over the robot technology and many of the related robot appliances are being used extensively also. Here represents the technology that proposed the working of robot for Floor cleaning. This floor cleaner robot can work in any of two modes i. e. "Automatic and Manual". All hardware and software operations are controlled by AT89S52 microcontroller. This robot can p...

the GRS is a one of the important units in Erbil Power Station EPS, which is responsible on controlling gas pressure and gas temperature this unit previously works manually. The local control panel for GRS system contains two types of digital signals the first one indicated by Light Emitting Diodes LED to point normal operations, fault and alarm, and event of operations while the second indicat...

We present a mathematical framework for general overand underdetermined hybrid (switched) systems of differential-algebraic equations (HDAEs). We give a systematic formulation of HDAEs and discuss existence and uniqueness of solutions, the treatment of the switch points and how to perform consistent initialization at switch points. We show how numerical solution methods for DAEs can be adapted ...

Being a unique phenomenon in hybrid systems, mode switch is of fundamental importance in dynamic and control analysis. In this paper, we focus on global long-time switching and stability properties of conewise linear systems (CLSs), which are a class of linear hybrid systems subject to state-triggered switchings recently introduced for modeling piecewise linear systems. By exploiting the conic ...

In this paper, we present the comparison result of M factor between free running and Q-switched mode of Nd:YAG laser. The system consists of sensitive infrared IR detector, lenses, distance scanner and a single array detector. Developed photographic paper was used to detect the invisible of IR beam which instantly and permanently records the beam spot. The beam spot was scanned and send to comp...
