Multi-motor coordination control system

Abstract

A multi-motor coordinated control system includes a reference speed given module and at least three motor control mechanisms, the reference speed given module is connected to the proportional modules of each motor control mechanism, and also includes a first-type controller and a second-type controller, The proportional module is connected to the electric drive module through the comprehensive summation node, and the output of the motor drive module is connected to the object module; the outputs of the front and rear motor control mechanisms are connected to the output summation node at the same time, the output summation node is connected to the signal processing module, and the signal processing modules are connected respectively. The first type of controller and the second type of controller, the first type of controller is connected to the comprehensive summation node of the previous motor control mechanism, the second type of controller is connected to the comprehensive summation node of the latter motor control mechanism, and the previous motor control mechanism The output of the mechanism's electrical drive module is connected to the synthetic summing node of the latter motor control mechanism through a gain block. The present invention has good position tracking performance, eliminates output coordination errors, and realizes control without static error.

Description

technical field [0001] The invention relates to a multi-motor transmission coordination control system. Background technique [0002] Multi-motor drives are increasingly being used in electromechanical systems. The large number of synchronous control devices in large-scale electromechanical equipment is likely to cause high failure rates, inconvenient use and maintenance, and heavy maintenance workload, which seriously affects production. Study the principle and method of multi-motor transmission coordinated control of straight wire drawing machine, and realize the coordinated control of straight wire drawing machine, which can reduce equipment cost and improve system reliability and control management level, save energy and reduce consumption, and improve product output and quality and economic benefits of equipment operation. [0003] At present, there are two types of control structures mainly used in multi-motor coordinated control: non-coupling control structure and co...
