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...

In this paper, a novel non-smooth robust control approach is presented for robotic manipulators. By using decimal power rule in Lyapunov redesign methods, the conventional robust control for robot is improved. Our approach can achieve higher control precision with faster convergence speed. The formulations of estimating residual set and settling time have been initially established. The practic...

This paper presents a new compensation method for fully differential two-stage CMOS operational transconductance amplifiers (OTAs). It employs a hybrid cascode compensation scheme, merged Ahuja and improved Ahuja style compensations, for fast settling. A design procedure for minimum settling time of the proposed compensation technique for a two-stage class A/AB OTA is described. To demonstrate ...

Current research focuses on predicting and mitigating the impacts of high hydraulic loadings on centralized wastewater treatment plants (WWTPs) under wet-weather conditions. The maximum permissible inflow to WWTPs depends not only on the settleability of activated sludge in secondary settling tanks (SSTs) but also on the hydraulic behaviour of SSTs. The present study investigates the impacts of...

We study the structure and properties of hot MHD accretion onto a Kerr black hole. In such a system, the hole is magnetically coupled to the inflowing gas and exerts a torque onto the accretion flow. A hot settling flow can form around the hole and transport the angular momentum outward, to the outer edge of the flow. Unlike other hot flows, such as advectionand convection-dominated flows and i...
