This paper aims at discussing possible automation and control system architectures based on fieldbus networks in which the controllers can be implemented either in a centralized or in a distributed form.
The decision follows a series of near-catastrophes on runways, including one this summer in which the controllers' radar system was blinded by rain.
IT IS always nice to be proved right, and that is the happy position in which the controllers of WMAP, an orbiting observatory designed to look at the beginning of the universe, find themselves.
In order to address this issue, many results have been given and verified by many researchers with a two steps process, in which the controller design and the control allocation process are independently carried out.
And the control stage, in which the controller performance is obtained when the load torque is changed.
The pilot had requested "flight following," a service that is offered by air traffic control in which the controller will point out other traffic in the area, but the service is never guaranteed; it is offered "workload permitting".
The first one is a theoretical framework for the stability analysis of nonlinear feedback control systems, in which the controller ˆf is an approximation identified from data of an ideal inverse model fo.
Next, a decentralized adaptive neural control method is proposed based on Lyapunov stability theory, in which the controller is designed to decrease the number of learning parameters.
This observation has led to the concept of "iterative identification and control design" and, subsequently, to model-free iterative controller design, in which the controller parameters are iteratively tuned on the basis of successive experiments performed on the real plant, leading to better and better closed loop behaviour.
ICAP is the first interface, in which the controller is an intellectual property (IP) entity implemented in the FPGA.
We consider a setting in which the controller, in addition to applying feedback, selects and varies the sampling rate.
