Abstract: A system and method for controlling an AC motor drive includes a control system programmed with an algorithm configured to optimize operation of the motor drive. Specifically, the control system is programmed to input an initial voltage-frequency command to the drive. The initial voltage-frequency command includes a voltage reference and a frequency reference corresponding to an operating point of an initial voltage/frequency (V/Hz) curve. The control system monitors a real-time output of the drive, modifies the voltage reference based on the real-time output of the drive, and transmits a modified voltage-frequency command to the drive. The modified voltage-frequency command corresponds to an operating point of a modified V/Hz curve defined by the modified voltage reference and the initial V/Hz curve.

Abstract: A modular framework for data import/export in an application that allows modules/components to be independently developed for importing and exporting data related to specific entities, including the handling of dependencies between entities. The framework is metadata driven which allows new entities to be introduced in the application with new modules for importing/exporting data related to those entities, without updating modules for exporting existing entities. Each type of entity is defined with a schema that represents the logical entity such that the entity is agnostic as to how the entity data is stored in database tables. A master configuration file is created for the application that lists each entity that can be imported or exported by the application, and defines how the framework imports or exports the business entity. Additionally, dynamic batching is provided to divide large datasets into multiple batches for suitable consumption by consumers of the exported data.
