We analyze under which conditions linear time-invariant state space systems can be stabilized by static linear state feedback such that prescribed transient bounds hold pointwise in time for the trajectories of the closed loop system. We introduce the concepts of (M,β)-stability and quadratic (M,β)-stability which guarantee a transient bound M along with a decay rate β < 0. Necessary and suffic...

A state-variable-based approach to the impulse response and convolution analysis of distributed microwave circuits is developed. The state-variable approach minimizes computation time and memory requirements. It allows the use of parameterized nonlinear device models, thus improving robustness. Soliton generation on a nonlinear transmission line is considered as an example.

The aim of this paper is reduction of torque and flux ripples in transient and steady state response of Direct Torque Control (DTC) for Induction Motor drive using intelligent technique. This proposed control to improve the torque, speed and flux response will be achieved with the Artificial Neural Network (ANN) DTC than the Conventional DTC (CDTC). In this paper DTC system using ANN is success...

Environmental impact assessment is becoming indispensable for the design and operation of chemical plants. Structured and consistent methods for this purpose have experienced a rapid development. The more rigorous and sophisticated these methods become, the greater is the demand for convenient tools. On the other hand, despite the incredible advances in process simulators, some aspects have sti...

A combination of two complex normalized least mean square (NLMS) adaptive filters that adapt on the same input signal at the same time is investigated. One of the filters has a large and the other one has a small step size. The outputs of the filters are combined together through a mixing parameter λ . This combination is an interesting new way of achieving simultaneously a fast initial converg...

In this study, the authors use the finite element method to model and analyse a cylindrical copper shelled SLA electrode for EDM operations, which is investigated experimentally in literature. A uniform silver paint thickness and copper shell thickness is assumed around the SLA epoxy core. In the experiment, 2-D analysis was used due to the axissymmetric shape, and steady state and transient di...

In contrast to previous common wisdom that epidemic activity in heterogeneous networks is dominated by the hubs with the largest number of connections, recent research has pointed out the role that the innermost, dense core of the network plays in sustaining epidemic processes. Here we show that the mechanism responsible of spreading depends on the nature of the process. Epidemics with a transi...

Steady-state isotopic-transient kinetic analysis (SSITKA) is a very useful technique for the kinetic study of heterogeneous catalytic reactions. Initially developed by Happe1,l Bennett,2 and Biloen? SSITKA has been used in a number of studies to determine in situ kinetic information about the reaction mechanism and the catalyst-surface reaction intermediates. The technique is based upon the det...

A differential pressure transmitter with an orifice is widely used as a flowmeter. A major drawback of this type of flowmeter is blockage of the impulse line, which connects the differential pressure transmitter to the orifice tap. A diagnostic method based on the amplitude of pressure fluctuations in the impulse line can be used to diagnose a blockage in the steady state; however, there is the...

AbstractThis paper is aimed at investigating the steady state and transient analysis behaviour of a squirrel cage induction generator of wind farm connected to a variable stiffness grid using MATLAB/SIMULINK. Different types of faults including three-phase-to-ground, double-line-toground, line-line and single-line-to-ground are studied. The calculated temporal variations of speed, voltage, acti...
