More Information
Summary:In the modern world, residents of large cities cannot imagine their life without elevators. This vertical movement vehicle is used in all types of urban infrastructure buildings, such as residential buildings, office and shopping and entertainment centers, hospitals, enterprises, etc. The design and control system of elevators are constantly developing and improving, as well as increasing safety requirements and the quality of the lift mechanisms. Elevator installations with control from frequency converters, which entail significant material costs, are gaining more and more popularity. Achieving a constant supply voltage is one of the most important tasks, since the less fluctuations and voltage drops in the system, the longer the service life of the equipment. In addition, the stability of the control systems and actuators depends on this. Considering all of the above, this work is aimed at improving the positioning accuracy of both outdated and modern control systems, taking into account the current norms and requirements for operation, subject to saving financial costs.
