Adaptive Control of a Solar Furnace for Material Testing

Control of a Solar Furnace using MPC with Integral Action

Solar furnaces are devices employed in high temperature material stress tests that use concentrated solar energy. This process has a nonlinear dynamics caused by a fourth power temperature term and by the nonlinear behavior of the shutter. Sun power variability due to weather conditions may affect the operation of a solar furnace if it is not compensated by adjusting the shutter aperture. The c...

Identification and adaptive control of a glass furnace

The Research Group for Automation of the Central Research and Design Institute for Silicate Industry (CRDISI) has been working for some years on the automation of technological processes in the silicate industry, in cooperation with the Department of Automation of the Technical University of Budapest (DATU). CRDISI yields the technological background, provides for the hardware tools and the bas...

Fuzzy adaptive tracking control for a class of nonlinearly parameterized systems with unknown control directions

This paper addresses the problem of adaptive fuzzy tracking control for aclass of nonlinearly parameterized systems with unknown control directions.In this paper, the nonlinearly parameterized functions are lumped into the unknown continuous functionswhich can be approximated by using the fuzzy logic systems (FLS) in Mamdani type. Then, the Nussbaum-type function is used to de...

Can We Apply the Control Material from Standard Clinical Chemistry Analyzer for Usage in the Point of Care Testing Analyzer?

Adaptive Optics Control for Laser Material Processing

An adaptive optics system is used for correcting tip-tilt disturbances in an experimental laser material processing setup. The proposed tip-tilt controller is based on PI-controllers that are fed with disturbance estimates from a Kalmanfilter. In addition, delays due to wavefront computation in the wavefront sensor and from data transmission are taken into account in the loop-shaping design. La...
