Robust adaptive control techniques have always been used in numerous industrial applications. In this paper, the dead-zone technique is used to damp growing oscillations in flexible AC transmission systems (FACTS) which is regarded as a new control mechanism for FACTS. The developed controller will overcome the arising problems due to the uncertainty of system parameters and disturbances acting on...
Adaptive control theory has been recently used in damping the growing oscillations in power systems, enhancing the system response and improving system dynamic stability. This paper proposes a new robust adaptive control mechanism for FACTS. The adopted concept is the dead-zone modification based on model reference adaptive control (MRAC) technique. The developed controller aims to overcome the variation...
In literature, design of model reference adaptive control (MRAC) schemes and adaptive laws has always been developed based on Lyapunov stability theory. Over the past few decades, it has been a common practice to use quadratic Lyapunov functions (QLFs). In contrast to such development and as a continuation to the research effort earlier published by the same authors, this paper involves the use of...
Adaptive control laws are modified to obtain robust adaptive control schemes in the presence of disturbance. One of the well known modifications in robust adaptive control is the e-modification scheme; this modification has always been developed based on Lyapunov stability theory using the standard form of quadratic Lyapunov function (QLF). In contrast to such development and as a continuation to...
