Review Of Self-Tuning Controller And Its Application In Electrical Power System

Abstract Self-tuning controller STC is one of the techniques of adaptive control. The controller is called self-tuning since it has the ability to adjust its own parameters according to the system conditions to obtain satisfactory control performance. This adaptive controller is developed to overcome the shortcomings of the non-adaptive controllers. This control technique is very popular and has been implemented in many important engineering applications. One important application of STC is in the field of electrical power engineering where the STC concept has been employed to design the self-tuning stabilizer for damping of power oscillation. This paper provides an overview on the self-tuning controller and its application in improving dynamic performance of an electrical power system.
