System and Method for Controlling the Operation of an Electric Motor of a Compressor

Abstract

The present invention refers to a system for controlling the operation of an electric motor of a compressor, comprising at least one predictive speed control loop (4) constituted by at least one speed controller (41), at least one processing core (42) and at least one signal delay circuit (43), wherein an output signal of said predictive loop (4) is added to the output signal of the outer speed control loop (1). It also relates to a method for controlling the operation of an electric motor of a compressor, comprising at least one step for discretizing a first refrigeration cycle (CR1) into a plurality of virtual sectors (J) in accordance with a previously known sampling rate, at least one step for determining the speed correction factor in each virtual sector (J) of the first refrigeration cycle (CR1), at least one step for discretizing a subsequent refrigeration cycle (CR1) into a plurality of virtual sectors (J) in accordance with a sampling rate used in the discretization of the first refrigeration cycle (CR1), and at least one step for applying each speed correction factor of the first refrigeration cycle (CR1) in the equivalent virtual sectors (SVN) of the subsequent refrigeration cycle (CRN).
