Zonal control of lumped systems on different classes of feedback functions
نویسنده
چکیده
In this work we investigate a class of feedback control problems for dynamic, in the general case, nonlinear objects involving lumped parameters. For synthesized control actions we introduce the notion of zonality that means constancy of the synthesized control parameters’ values in each of the subsets (zones). These subsets are obtained by partitioning the set of all possible states of the object investigated. Formulas for the gradient of the target functional with respect to the optimizable parameters of the synthesized controls are obtained. These formulas can be used to build numerical solution schemes on basis of first order iterative optimization methods. Results of numerical experiments obtained by solving some test problems are given. Let the controlled process be described by the following nonlinear differential equations system:

ADAPTIVE FUZZY OUTPUT FEEDBACK TRACKING CONTROL FOR A CLASS OF NONLINEAR TIME-VARYING DELAY SYSTEMS WITH UNKNOWN BACKLASH-LIKE HYSTERESIS
This paper considers the problem of adaptive output feedback tracking control for a class of nonstrict-feedback nonlinear systems with unknown time-varying delays and unknown backlash-like hysteresis. Fuzzy logic systems are used to estimate the unknown nonlinear functions. Based on the Lyapunov–Krasovskii method, the control scheme is constructed by using the backstepping and adaptive techniqu...
متن کاملZonal Feedback Control Problems for Non-linear Dynamic Systems
1. Introduction Feedback control problems have been investigated by a lot of authors. The interest to this class of problems has increased for the last years due to the development of technical, computational, and measuring facilities of monitoring and of controlling technical and technological objects. They generally considered linear systems, and in case of non-linear systems corresponding li...

متن کاملAdaptive Consensus Control for a Class of Non-affine MIMO Strict-Feedback Multi-Agent Systems with Time Delay
In this paper, the design of a distributed adaptive controller for a class of unknown non-affine MIMO strict-feedback multi agent systems with time delay has been performed under a directed graph. The controller design is based on dynamic surface control method. In the design process, radial basis function neural networks (RBFNNs) were employed to approximate the unknown nonlinear functions. S...
متن کاملDesign of Observer-based H∞ Controller for Robust Stabilization of Networked Systems Using Switched Lyapunov Functions
In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
