The control and management of AC and DC microgrids is a major area of research addressing some of the key challenges like the integration of renewable energy sources (RES), source optimization, and stability issues etc. Numerous microgrid control strategies have been proposed and examined earlier. However, the control becomes even more susceptible to instability due to the participation of intermittent...
A method is proposed to significantly improve the transient performance of Signal Transformation Approach (STA). For triangular reference signals, the proposed method is shown to be equivalent to a recently proposed hybrid control method, known as Impulsive State Multiplication (ISM), if the compensator contains at least two integrators. Effectiveness of the proposed method in tracking of arbitrary...
A repetitive controller has been applied owing to its prominent capability for attenuating periodic disturbances and/or tracking periodic reference commands. A repetitive controller is generally added on the existing feedback control system to improve the tracking performance. However, the repetitive controller has been designed without utilizing the effective information such as the performance weighting...
The IntelRate controller does not require to evaluate some critical network parameters (such as the bottleneck bandwidth and the number of flows in the link) while performing well to the sudden changes in traffic load or bandwidth. This paper demonstrates theoretically that the IntelRate control system is globally asymptotically stable. Opnet simulations verify that the IntelRate controller can maintain...
EMKC is an explicit congestion control algorithm which is designed for high bandwidth delay product (BDP) networks. Although delay-independence is an appealing characteristic, the EMKC system developed in exhibits undesirable equilibrium properties and slow fairness convergence behavior. To overcome these drawbacks, we propose a new method called AEMKC (Advanced Exponential Max-Min Kelly Control)...
