High gain feedback control
Informally, a controller designed for a particular set of parameters is said to be robust if it also works well under a different set of assumptions. High-gain feedback is a simple example of a robust control method; with sufficiently high gain, the effect of any parameter variations will be negligible. From the closed-loop transfer function perspective, high open-loop gain leads to substantial disturbance rejection in the face of system parameter uncertainty. Other examples o… WebDescription. For over a quarter of a century, high-gain observers have been used extensively in the design of output feedback control of nonlinear systems. This …

WebThe feedback control system is composed of sensors, controllers, process systems, etc. The major components of a feedback control system are input, the process which is being controlled, output, sensing elements, controllers, and actuating devices. The feedback control would only need minimal knowledge of the process that is to be controlled.

WebIn this paper, an adaptive fuzzy decentralized robust output feedback control approach is proposed for a class of large-scale strict-feedback nonlinear systems without the … WebThe use of high-gain observers in feedback control appeared first in the context of linear feedback as a tool for robust observer design. In their celebrated work on loop transfer recovery [1], Doyle and Stein used high-gain observers to recover, with observers, frequency-domain loop properties achieved by state feedback. The investigation of ...
