DISTURBANCE REJECTION IN NONLINEAR SYSTEMS USING NEURO-FUZZY MODEL

The problem of disturbance rejection in the control of nonlinear systems with additive disturbance generated by some unforced nonlinear systems, was formulated and solved by {itshape Mukhopadhyay} and {itshape Narendra}, they applied the idea of increasing the order of the system, using neural networks the model of multilayer perceptron on several systems of varying complexity, so the objective...

Voltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control

Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent.  This controller is used in a double loop structure including an inner current loop and oute...

Investigation of Periodic-Disturbance Identification and Rejection in Spacecraft

Spacecraft periodic-disturbance rejection using a realistic spacecraft hardware simulator and its associated models is investigated. The effectiveness of the dipole-type disturbance rejection filter on the current realistic nonlinear rigid-body spacecraft model is validated. However, it is shown that the rejection filter is not robust to disturbance frequency uncertainty. Therefore, system iden...

Discrete-time Adaptive Feedback Disturbance Rejection using a Retrospective Performance Measure

ABSTRACT A discrete-time adaptive feedback disturbance rejection algorithm is developed for applications where the disturbance spectrum is unknown. Feedforward control methods are frequently used to reject disturbances with a known spectrum, but a feedback controller is required when the disturbance is unknown. Multi-input multi-output (MIMO) disturbance rejection algorithms are developed for c...
