Optimal Control of a HVDC Transmission Link
TLDR
In this article, the state regulator and tracking techniques have been used to design controller feedbacks to improve system performance and an eigenvalue search technique has also been applied to determine the desired controller gain and time constant.Abstract:
This paper applies the modern control theory to design HVDC controllers. The state regulator and tracking techniques have been used to design controller feedbacks to improve system performance. Both optimal and sub-optimal controllers have been designed. An 'eigenvalue search' technique has also been applied to determine the desired controller gain and time constant. Using the various designed controllers, the dynamic performance of the system has been studied on both a digital computer and a small scale simulator. Some of these time domain studies are included in addition to the root locus plots.read more
