Adaptive Control Mixer Method

An adaptive offset cancellation mixer for direct conversion receivers in 2.4 GHz CMOS

In this paper we present a new circuit design for a 2.4GHz CMOS direct conversion mixer incorporating adaptive offset cancellation. The basic circuit structure is that of a Gilbert cell mixer. Offsets are cancelled by dynamically varying the bias on the loads, which are designed to provide constant impedance independent of the load cancellation current. The bias control is regulated via an adap...

The Robust Control Mixer Module Method for

Control of an Industrial Mixer using PLC

This paper is a design and implementation of a monitoring and control system for industrial mixer using PLC .This mixer used for an effective, reliable and highly flexible method for the control of processes within an Industrial environment. The objective of this study is to simulate the control an industrial mixer and by doing this we can develop a program that can be used for the actual imple...

An adaptive neuro-fuzzy inference system as a soft sensor for viscosity in rubber mixing process

Mixing rubber in an internal mixer is a complex nonlinear process in which viscosity of the rubber is one of the key quantities concerning end product quality. Since viscosity can’t be measured online, soft sensor methods for modelling viscosity are investigated to establish an online control of viscosity. This paper presents a black-box approach to modelling viscosity using an adaptive neuro-f...

Framework for adaptive fluid-structure interaction with industrial applications

We present developments in the Unicorn-HPC framework for unified continuum mechanics, enabling adaptive finite element computation of fluid-structure interaction, and an overview of the larger FEniCS-HPC framework for automated solution of partial diffential equations of which Unicorn-HPC is a part. We formulate the basic model and finite element discretisation method and adaptive algorithms. W...
