On the Design of Variable Structure Load Frequency Controllers by Tabu Search Algorithm: Application to Nonlinear Interconnected Models

摘要: A variable structure controller (VSC) with chattering reduction feature applied to interconnected load frequency control (LFC) problem is presented. Formulating the design of VSC as an optimization and utilizing tabu search (TS) algorithm provides a simple systematic way arriving at optimal feedback gains switching vector values controller. In addition, this will cut down need for nonlinear or coordinate transformation reported before. The tested LFC model incorporates nonlinearities in terms generation rate constraint (GRC) limiter on integral value. order guarantee enhancement system, dynamical performance VSC, different objective functions were investigated process. complexity reduced by using only accessible states designing VSC. Comparison previous methods literature validates significanc...
