Abstract

The invention relates to a one-to-many control system of an industrial frequency converter for a textile machine and a realization method. Generally, the traditional frequency can only drive one or two three-phase motors to run. The one-to-many control system comprises a singlechip microcomputer module, an FPGA (Field Programmable Gate Array) module, a man-machine interactive interface device, a serial communication device module, a power drive device and a three-phase motor device. The singlechip microcomputer is used for receiving and processing an instruction sent by the man-machine interactive interface device and sending processed data to the FPGA module through an SPI (Serial Peripheral Interface). The FPGA module is used for performing calculation to obtain a phase increment by means of an embedded CORDIC (Coordinated Rotation Digital Computer) algorithm, obtaining an angle value according to calculation, processing the angle value to serve as an SPWM (Sinusoidal Pulse Width Modulation) sinusoidal pulse duration control word, outputting an SPWM pulse, controlling an IPM module of an appointed group in the power drive device to output a three-phase SPWM pulse and driving the corresponding three-phase motor to run. The one-to-many control system can be used for controlling more than two three-phase motors to run.

Description

technical field [0001] The invention relates to an industrial frequency converter, in particular to an industrial frequency converter one-to-many control system for textile machinery and a realization method. Background technique [0002] Most of the existing industrial inverter control systems are controlled by one inverter control system to drive a three-phase motor (one drive one), or one inverter control system controls two three-phase motors (one drive two) . This type of frequency converter will not be able to complete the occasion where two or more three-phase motors are to be controlled simultaneously. Contents of the invention [0003] The purpose of the present invention is to propose an industrial frequency converter for textile machinery, one-to-many control system and its realization method, aiming at the deficiencies of the prior art. [0004] The one-to-multiple control system of the industrial frequency converter for textile machinery of the present inven...
