By increasing electric power demand, powers systems can reach stress conditions, resulting in undesirable voltage and frequency condition. Nowadays It is well recognized that by applying the flexible AC transmission system (FACTS) controllers, the stability limits can be enhanced significantly. In this paper an optimized self tuning fuzzy PI controller (STFPIC) is proposed for the UPFC to improve...
In this paper, the self-tuning PID control law based on generalized minimum variance control law is applied for DC-DC converter circuit. Control performance is ascertained self tuning law better than fixed parameter when system changed. In this instance, lambda, design parameter set from the start. But, challenges for the future can be able to handle auto-tuning of control weighting factor.
An adaptive-step-size auto-tuning algorithm and controller for power converters' switching frequency optimization with improved convergence performance is presented in this paper. The controller automatically tracks and determines the switching frequency of a power converter in order to achieve the highest power conversion efficiency under variable operating conditions including temperature variation...
