Further results on the disturbance response of a double integrator controlled by saturating linear static state feedback

چکیده
In this paper we study the response to external disturbances of a double integrator with saturating feedback. For a class of disturbances that have bounded integrals over all intervals, we show that a linear static feedback law can always be designed to ensure boundedness of the states. Moreover, boundedness can be preserved if the disturbance is biased by a small DC signal. In the special case that the disturbance is made up of a finite number of sinusoids and a small bias, any linear static feedback ensures boundedness of the states. These results are an extension of previous results by Wen, Roy, and Saberi (2008).

متن کاملOn the External Stability of Linear Systems with Actuator Saturation Constraints, and the Decentralized Control of Communicating-Agent Networks with Security Constraints By
by Zheng Wen, M.S. Washington State University August 2007 Co-Chairs: Ali Saberi and Sandip Roy This thesis is motivated by the need to better understand the analysis and control of linear systems subject to constraints. We contribute to this field by pursuing research on two specific topics: 1) the external stability of linear systems subject to actuator saturation, and 2) the security of Comm...
متن کاملStabilization of Networked Control Systems with Variable Delays and Saturating Inputs
In this paper, improved conditions for the synthesis of static state-feedback controller are derived to stabilize networked control systems (NCSs) subject to actuator saturation. Both of the data packet latency and dropout which deteriorate the performance of the closed-loop system are considered in the NCS model via variable delays. Two different techniques are employed to incorporate actuator...
متن کاملOptimum parameters of nonlinear integrator using design of experiments based on Taguchi method
For many physical systems like vehicles, acceleration can be easily measured for the respective states. However, the outputs are usually affected by stochastic noise disturbance. The mentioned systems are often sensitive to noise and structural uncertainties. Furthermore, it is very difficult to estimate the multiple integrals of the signal, acceleration to velocity and velocity to position. In...
متن کاملAdaptive Speed Control of Three-Phase Induction Servo-drives Based on Feedback Linearization Theory
In this paper, based on feedback linearization control method and using a special PI (propotational integrator) regulator (IP) in combination with a feed-forward controller, a three-phase induction servo-drive is speed controlled. First, an observer is employed to estimate the rotor d and q axis flux components. Then, two input-output state variables are introduced to control the dynamics of to...
