Modeling, Identification and Control
1997We study the interactions between modeling, identification and control, in the situation where the only purpose of the modeling or identification is the design of a high performance controller. This leads us to suggest that the model building criterion should be determined by the control objective, leading to identification on the basis of closed loop ...

Nonlinear identification and control of aircraft
International Journal of Systems Science, 2000The major goal of this paper is to approach and solve a spectrum of extremely important problems in nonlinear analysis, identification, optimization, and control of current and next generation advanced aircraft. High-performance aircraft must satisfy the required performances in the specified operational flight envelope at various attitudes and ...

Integrated identification and robust control
Journal of Process Control, 1997Abstract A framework for integrated identification and control is presented. As part of this framework, frequency domain uncertainty bounds are derived for robust stability tests, a robust stability test for elliptical bounds is developed for SISO systems, a methodology for estimating controller performance is derived, and an optimal experiment ...

Identification of the Chromosomes that Control Malignancy
Nature New Biology, 1973ACCORDING to a model which we have proposed for the genetic control of malignancy1, malignant cell transformation and its reversion are controlled by the balance between genes for expression (E) and suppression (S) of malignancy. These genes may be located on different chromosomes; E exists in normal cells but is neutralized by S and malignancy is ...

Identification for robust inferential control
Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009High measured performance does not imply that the true system performance is satisfactory. Indeed, in many systems, these performance variables cannot be measured directly and have to be inferred from the measured variables by using model knowledge. The aim of the present paper is to develop an identification and control design approach that can deal ...

Complexity control in semantic identification
International Journal of Intelligent Systems Technologies and Applications, 2006This work introduces an efficient scheme for identifying semantic entities within multimedia data sets, providing mechanisms for modelling the trade-off between the accuracy of the result and the entailed computational cost. Semantic entities are described through formal definitions based on lower-level semantic and/or syntactic features.

Pertussis: Identification, Prevention and Control
2019Pertussis is a vaccine-preventable disease. Despite the high vaccination coverage among children, pertussis is considered a re-emerging disease for which identification, prevention and control strategies need to be improved. To control pertussis it is important to maintain a high vaccination coverage to protect the age groups considered at high risk ...

An integrated identification methodology for control and identification
International Journal of Systems Science, 1992An integrated identification methodology (IIM) is presented that appropriately combines expert systems and adaptive identification technologies for process control systems. Since many physical systems have both numerical and non-numerical characteristics, both qualitative and quantitative descriptions of the characteristics are proposed in the IIM for ...

Identification and Control of Asbestos Exposures
American Industrial Hygiene Association Journal, 1971Asbestos can be used safely in modern industrial technology if adequate precautions are taken to prevent excessive and unsuspected exposures. To distinguish between asbestos and other fibers, new techniques must be applied to electron microscopy and diffraction, emission and atomic absorption spectrophotometry, electron microprobe, and neutron ...

On-line identification and control methods for PID controllers
2010 11th International Conference on Control Automation Robotics & Vision, 2010The aim of this paper is to present a method for on-line tuning of PID controller for stable processes. Without breaking closed-loop control, an explicit process model is developed from a single relay test and then controller gains are re-tuned non-iteratively to improve the performance.
