In this paper, we propose a new optimized PID controller to stabilize the synchronous machine connected to an infinite bus. The model for the synchronous machine is 4-ordered linear Philips-Heffron synchronous machine. In this research, the parameters of the PID controller are optimally achieved by minimizing a definite fitness function to removes the unstable Eigen-value to the left side of im...

Around 50 years ago, Edmund Phelps and Robert Lucas proposed an answer to the question why changes in aggregate nominal spending bring about output employment effects, instead of purely proportional variations prices. The Phelps-Lucas monetary misperception hypothesis asserted that imperfect information state economy may cause sluggish price or wage adjustment emerge as reactions shocks otherwi...

Philips Semiconductor is a supplier to a wide range of markets for analogue and mixed-signal consumer ICs. These products extend from the simplest form of linear products to advanced VLSI analogue systems such as the One-Chip TV. For new mixed-signal products Philips has started to adopt a strategy of testing similar to that used for digital ICs. This is based on efficiently proving the product...

in the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. in this study, a series of compression tests were simulated using abaqus software. in this study, it has been employed the taguchi method to design experiments by the factor...
