Adaptive Control of Electrical Power Generating Systems Using The Properties of Variable Structure Systems (VSS).(Dept.E)

Abstract

In the present p ap er, a new algorithm for solving the control law in electrical power systems, is introduced. This new algorithm is based on the sliding mode prop erty, existing in variable structure systems (VSS). The resulting control law is discontinuous by its nature. However, it does not require informations about the system parameters or its manner of variation. The only requirements are the maximum and minimum limits of variation for each p arameter. An adap tive controller is designed, for an electrical p ower system, on the basis of that new algorithm. The main function of the controller 18 the adap tive control of the electrical power system, Meanwhile, it can be used as an observer Theoretical and comp utetional results, using that controller insure the adaptive control p roperty in the electrical power system model. The adaptive prop erty verifies under rapid and wide range of parameters variation and also under the effect of a unit step external disturbance.
