Improvement of the Load Frequency Control Using Pole-Placement Technique

Abstract

The classical design techniques that used for load frequency control are based on the root- locus that utilizes only the plant output for feedback with a dynamic controller. In this paper ,a new control technique known the pole-placement design is used to control the frequency and require the use of all state variables to form a linear static controller. The pole placement design allows all root of the characteristic equation to be placed in the desired location. This result will be in a regulator with constant gain vector K .The poles in this technique refer to the root of the characteristic equation and this poles are chosen arbitrary in order to find the best frequency deviation response . Different techniques of the load frequency control such as integral controller, PID controller and the pole placement controller are used and compared with each other to find the best techniques. Due to this comparison the pole placement design is the best technique for load frequency control. The programs are written using matlab package.
