Two Degrees of Freedom Observer Controller for Load Frequency Control with Communication Delay
Abstract: Two degrees of freedom (2-DOF) Smith predictor based observer controller is designed for load frequency control of two area systems with communication delay. The conventional proportional integral (PI) controller is used for command tracking and an independent observer based feedback controller is designed for disturbance of change in load demand. In interconnected power system, the presence of communication delay complicates the design and implementation of the controller. The original delayed …

Parameter Identification of Vibrating MIMO Mass-Spring-Damper Mechanical Systems with Coulomb Friction
Abstract: This study presents a time-domain method for identifying parameters in multi-degree-of-freedom (DOF) linear mass-spring-damper systems that include Coulomb friction, where the friction coefficient varies within a limited range, using measurements of position and control force. For mass identification in single-degree-of-freedom (DOF) vibrating mechanical systems with stiffness and no damping but Coulomb friction, the friction term is eliminated by first derivative processing. In addition, the identification of the coefficient of friction …
