An Adaptive Internal Model-based Controller for Periodic Disturbance Rejection
This paper details the design of an adaptive internal model-based controller to attenuate periodic disturbances in the presence of random noise. The internal model-based controller is designed in two steps, making use of the separation principle to design a controller with the desired properties that stabilizes the closed-loop system. Periodic disturbances appear as harmonics of a fundamental f...
متن کاملState-dependent periodic adaptive disturbance compensation
The state-dependent nonlinear external disturbance compensation problem is considered. No prior information about the disturbance is assumed except the periodicity of the disturbance with respect to a state variable, which is termed a ‘state-dependent periodic disturbance.’ The key idea of the proposed new adaptive compensation method is to make use of this known state-dependent periodicity. In...
متن کاملAnalysis of periodic growth-disturbance models.
In this paper, I present and discuss a potentially useful modeling approach for investigating population dynamics in the presence of disturbance. Using the motivating example of wildfire, I construct and analyze a deterministic model of population dynamics with periodic disturbances independent of spatial effects. Plant population growth is coupled to fire disturbance to create a growth-disturb...
متن کاملApplication of Adaptive Disturbance Observer Control to an Underwater Manipulator
Hydrodynamics of the manipulator mounted on the vehicle are poorly known and time-varying. Furthermore, its motion is disturbed by the vehicle motion and current. This paper presents a non-regressor based adaptive control scheme with a disturbance observer for tracking the trajectory of underwater mobile platform-mounted manipulators. The presented control system does not require any informatio...
متن کاملExperimental Evaluation of Disturbance Observer-based Vibration Suppression and Disturbance Rejection Control in Torsional System
Abstract. In the resonance ratio control, the estimation speed of the disturbance observer should have been much faster than the resonance frequency of the controlled system. However, too fast disturbance observer causes implementation problem. In this paper, we give the optimal speed of the disturbance estimation and propose a novel technique, slow resonance ratio control, which enables us to ...
