The research on high-performance vector control of permanent magnet synchronous motor (PMSM) drive system plays an extremely important role in electrical system. To further improve the speed performance system, a fast non-singular end sliding mode (FNTSM) surface function based traditional NTSM is developed. theoretical analysis proves that FNTSM has faster dynamic response and more finite-time...

In seaports, low-carbon energy systems and efficiency have become increasingly important as a result of the evolution environmental climate change challenges. order to ensure continued success technological advancements must be introduced number systems, such seaport vehicles, harbor cranes, power sources berthed ships. Harbor areas might need microgrid handle these aspects. Typically, microgri...

control of well drilling operations poses a challenging issue to be tackled. the loss of well control could lead to the occurrence of blowout as a severe threat, involving the risk of human lives and environmental and economic consequences. conventional proportional-integral (pi) controller is a common practice in the well control operation. the small existing margin between pore pressure and f...

in this paper, we try to use modeling based on singular perturbation theory, in order to control satellite attitude during the wide rolling angle maneuvering through nonlinear h∞ control strategy. differential equations describing dynamics of the satellite are presented first, and by choosing the appropriate dynamic model for actuators and based on the standard singular perturbation model, the ...

In analog hardware, numbers can be represented by the location of active components in a pattern of fuzzy logic variables. This coding scheme is called place coding. In this case, fuzzy rule circuits can be implemented by only a fuzzy AND gate made of one MOS transistor per input. This approach is demonstrated by an analog integrated circuit solving a non-linear control problem.

Since its inception in the early 1980's, the SLC Control System has been driven by a highly structured memory-resident real-time database. While efficient, its rigid structure and file-based sources makes it difficult to maintain and extract relevant information. The goal of transforming the sources for this database into a relational form is to enable it to be part of a Control System Enterpri...
