A method for shortening of the settling time in all digital phase-locked loops is proposed. The method utilizes self monitoring to obtain the parameters necessary for feed-forward compensation. Analysis shows that by employing this technique both fast settling and good stability can be achieved simultaneously. Matlab and Verilog-AMS simulation shows that typical settling speed can be reduced to...

Continuous homogeneous controllers are utilized in a full state feedback setting for the uniform finite time stabilization of a perturbed double integrator in the presence of uniformly decaying piecewise continuous disturbances. Semiglobal strong C1 Lyapunov functions are identified to establish uniform asymptotic stability of the closed-loop planar system. Uniform finite time stability is then...

This paper deals with the design ripple-free deadbeat controllers for sampled-data systems. Given a prescribed settling time, the design problem is tackled by computing a ripple-free deadbeat controller that optimizes an H2 performance criterion. This criterion accounts for the quality of the tracking response and for the control energy necessary to achieve the deadbeat behavior. Our main resul...

This paper presents results of a series of experiments on the settling velocity of spheres in twocomponent solid-liquid suspensions. Particular emphasis has been given to the effective values of density and viscosity of the mixture which allows us to describe the settling of the spheres in the mixture using appropriate modifications of the equations valid for the settling of spheres in pure flu...

A model scald tank was constructed to study the mixing pattern of water in a poultry scalding system. Tank dimensions were approximately 6 m long by 10.5 cm wide with a water depth of 18 cm. Water was vigorously agitated with compressed air delivered through a 1.9-cm polyvinyl chloride pipe on the bottom of the tank. Food coloring was added to the tank at a single point, and water samples were ...

Remote sensing technology has been widely applied in various fields, including oil, gas, and mineral exploration, spatial planning, environmental monitoring. This paper describes the application of remote for potential study a renewable micro hydropower plant (MHP) using Landsat 8 satellite data. The Sukaati Watershed, West Java, Indonesia, was selected as case area. data, acquired on August 21...

Abstract The issues concerning mining have been causing a wide variety of emotions. Objection to and disagreement with new investments, but also social acceptance for the operation plants offering stable employment. Production in this sector is associated generation waste. In case copper ore mining, result entrepreneur's activity consists waste treatment facilities form post-flotation settling ...
