Multi-motor coordination control system

Abstract

The invention provides a multi-motor cooperative control system, comprising a reference speed given module, at least three motor control mechanisms, a first type of controller and a second type of controller, wherein, the reference speed given module is connected with proportion modules of each motor control mechanism, the proportion modules are connected with an electric drive module by integrated summation nodes, an output of the electric drive module is connected with an object module; the outputs of the front motor control mechanism and the rear motor control mechanism are connected with output summation nodes simultaneously, the output summation nodes are connected with a signal processing module which is respectively connected with the first type controller and the second type controller, the first type controller is connected with the integrated summation node of the front motor control mechanism, the second type controller is connected with the integrated summation node of the rear motor control mechanism, the output of the electric drive module of the front motor control mechanism is connected with the integrated summation node of the rear motor control mechanism by a gain module. The multi-motor cooperative control system has good location tracking performance, eliminates the output coordination error and realizes the non-steady-error control.

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...
