Discretized Model-Reference Feedback and Robust Stabilization on Integer Grid Coordinates
نویسنده
چکیده
This paper deals with a stabilizing and designing problem of discretized modelreference feedback control systems on integer grid coordinates. At present, all feedback control systems are realized using discretized signals. However, the analysis and design of discrete-time and discrete-value (point-to-point) control systems has not been established. In this paper, a robust stability condition for such control systems with multiple discretizations (nonlinearities) is presented in a frequency domain by using Ostrowski’s M-matrix expression. As a result, model-reference feedback control systems are sufficiently stabilized and well designed. Numerical examples are provided to verify the design method.

Model-Reference Discretized PID Control and Robust Stabilization for Continuous Plants
This paper deals with a designing problem of discrete-time and discrete-value (discretized) control systems based on a model-reference feedback structure. The model used in this study is assumed to be a second-order lag system that is expressed by a bilinear transformation. That type of discretized (nonlinear) control systems is presented and analyzed. The model reference feedback using a secon...
متن کاملRobust Stabilization for Discretized Control Systems on a Grid Pattern
This paper deals with the stability problem of discrete-time and discrete-value (discretized/quantized) control systems in a frequency domain. The discretized (stepwise) nonlinear characteristic on a grid pattern is partitioned into two sections: bounded and sectorial areas. First, by considering a sectorial area over a specified threshold, the robust stability condition for nonlinear discrete-...

Moreover, robust control laws are designed to guarantee the practical stability of the perturbe...
متن کاملRobust Quadratic Assignment Problem with Uncertain Locations
We consider a generalization of the classical quadratic assignment problem, where coordinates of locations are uncertain and only upper and lower bounds are known for each coordinate. We develop a mixed integer linear programming model as a robust counterpart of the proposed uncertain model. A key challenge is that, since the uncertain model involves nonlinear objective function of the ...
