چکیده مقاله:

This paper works on the concept of flatness and its practical application for the design of an optimal transient controller in a synchronous machine. The feedback linearization scheme of interest requires the generation of a flat output from which the feedback control law can easily be designed. Thus the computation of the flat output for reduced order model of the synchronous machine with simplified turbine dynamics is hereby presented. The corresponding linearized compensator is derived as well as the nonlinear controller for transient stabilization of a synchronous machine subjected to large disturbances.  The transient  behavior  of  a  single  machine equipped  with  the so designed  nonlinear controllers feeding an  infinite  bus  is illustrated  via  simulation  in  Matlab  environment. The results obtained for  transient disturbances on  the  single  machine infinite  bus  system  (SMIBS)  are  presented  and compared with other  control algorithms to demonstrate the effectiveness of the proposed scheme.

Time domain simulation of power systems with different time scales

The time evolution of power systems is modeled by a system of differential and algebraic equations. The variables involved in the system may exhibit different time scales. In standard numerical time integration methods the most active variables impose the time step for the whole system. We present a strategy, which allows the use of different, local time steps over the variables. The partitioni...

A Geometric Approach to Systems with Multiple Time Scales

Physical systems often involve several processes that are evolving on di erent time scales. The resulting equations have a speci c structure which can be exploited to great e ect and the kind of results that can be obtained, at least with a certain goal in mind, are the subject of this paper. On account of the physical motivation for the di erent scales, there are many areas in which applicatio...

A Novel Approach to Power Saving for Real-Time Systems

In recent years, energy efficiency gains more and more attention in real-time embedded system for the incerasing application of embedded system. Many methods have been developed by means of the Dynamic Voltage Scaling (DVS) which use the slack time to adjust supplied voltage so as to decrease the energy expense. Unfortunately, how to optimally adjust supplied voltage is a NP-complete problem. T...

A Novel Approach to Designing of Chattering-Free Sliding-Mode Control in Second-Order Discrete-Time Systems

In this paper, a chattering-free sliding-mode control is mainly proposed in a second-order discrete-time system. For achieving this purpose, firstly, a suitable control law would be derived by using the discrete-time Lyapunov stability theory and the sliding-mode concept. Then the input constraint is taken into account as a saturation function in the proposed control law. In order to guarantee ...
