MATLAB Software for Feedforward Optimal Control of Systems with Flow Varying Time Delays - Revision 2
نویسنده
چکیده
This report describes a software package for optimal control of a nonlinear system with flow variant time delay. The software was developed for control of a solar plant in Seville, Spain, and is tailored to this application. The optimization is performed using an algorithm with gradient based minimum search. PREREQUISITES This report only describes the software. The user is assumed to have a working knowledge of the algorithm upon which it is based, as well as of MATLAB. REVISIONS Revision 1: [1] describes revision 1.0 of the accompanying SW. The software has been tested with MATLAB 6.5, and MATLAB 7.0 running on PCs and UNIX workstations. Revision 2: The revision adds the possibility of choosing different parameters for the system and the model inside the controller, which enables evaluation of model error sensitivity. Further, an error in the simulator has been corrected. The error resulted in an erroneous time scale of the data saved at the end of the simulation loop.

ADAPTIVE FUZZY TRACKING CONTROL FOR A CLASS OF NONLINEAR SYSTEMS WITH UNKNOWN DISTRIBUTED TIME-VARYING DELAYS AND UNKNOWN CONTROL DIRECTIONS
In this paper, an adaptive fuzzy control scheme is proposed for a class of perturbed strict-feedback nonlinear systems with unknown discrete and distributed time-varying delays, and the proposed design method does not require a priori knowledge of the signs of the control gains.Based on the backstepping technique, the adaptive fuzzy controller is constructed. The main contributions of the paper...
متن کاملTime Delay and Data Dropout Compensation in Networked Control Systems Using Extended Kalman Filter
In networked control systems, time delay and data dropout can degrade the performance of the control system and even destabilize the system. In the present paper, the Extended Kalman filter is employed to compensate the effects of time delay and data dropout in feedforward and feedback paths of networked control systems. In the proposed method, the extended Kalman filter is used as an observer ...
متن کاملAn Optimal Dynamic Control Method for an Isolated Intersection Using Fuzzy Systems
Traffic flow systems are nonlinear and uncertain, so it is very difficult to find their optimal points. In traditional traffic control systems, the traffic lights of crossings change in a fixed time period that is not optimal. On the other hand, most proposed systems are sufficiently capable of coping with the uncertainties of traffic flow. To solve this problem, there is a need to develop expe...
متن کاملFINITE-TIME PASSIVITY OF DISCRETE-TIME T-S FUZZY NEURAL NETWORKS WITH TIME-VARYING DELAYS
This paper focuses on the problem of finite-time boundedness and finite-time passivity of discrete-time T-S fuzzy neural networks with time-varying delays. A suitable Lyapunov--Krasovskii functional(LKF) is established to derive sufficient condition for finite-time passivity of discrete-time T-S fuzzy neural networks. The dynamical system is transformed into a T-S fuzzy model with uncertain par...

In this paper, we are discuss about the issue of synchronization for singular complex dynamical networks with Markovian jumping parameters and additive time-varying delays through pinning control by Takagi-Sugeno (T-S) fuzzy theory.The complex dynamical systems consist of m nodes and the systems switch from one mode to another, a Markovian chain with glorious transition probabili...
