Input Estimation Techniques for Robust Output Tracking
نویسنده
چکیده
Abstract— A fundamental problem for control engineers is that of output tracking. The earlier approaches are restricted to certain classes of systems precluding the presence of zeros from certain regions in the complex plane, and do not reasonably take into account process and measurement noise. A technique to achieve output tracking applicable to non-minimum phase linear systems is presented wherein the desired signal is obtained from field measurements, and hence corrupted by noise. This method is then applied to helicopter hover control. Robustness is ensured via a two degree-of-freedom controller design. Keywords—linear systems, tracking, Kalman filter

Robust Control of Encoderless Synchronous Reluctance Motor Drives Based on Adaptive Backstepping and Input-Output Feedback Linearization Techniques
In this paper, the design and implementation of adaptive speed controller for a sensorless synchronous reluctance motor (SynRM) drive system is proposed. A combination of well-known adaptive input-output feedback linearization (AIOFL) and adaptive backstepping (ABS) techniques are used for speed tracking control of SynRM.

متن کاملDesign of robust carrier tracking systems in high dynamic and high noise conditions, with emphasis on neuro-fuzzy controller
The robust carrier tracking is defined as the ability of a receiver to determine the phase and frequency of the input carrier signal in unusual conditions such as signal loss, input signal fading, high receiver dynamic, or other destructive effects of propagation. An implementation of tight tracking can be understood in terms of adopting a very narrow loop bandwidth that contradict with the req...
