Abstract

The invention discloses a method for improving the rotating speed synchronous control performance of a dual-motor flexible connection transmission system, and aims to effectively suppress disturbance occurring inside and outside the system and improve the coupling coefficient selection range so as to enable the rotating speed of the dual-motor system to be kept synchronous. According to the technical scheme, the method comprises the steps: 1, taking mechanical kinetic equations of two motors as a whole, and establishing a uniform speed ring mathematical model with disturbance; 2) designing a unified speed ring controller unit of the double motors according to the unified speed ring mathematical model, wherein the controller unit is used for estimating and compensating disturbance information of the two motors; 3) acquiring rotating speed information of the two motors in real time through a rotating speed synchronization error unit and calculating a rotating speed synchronization error; 4) adjusting the rotating speed synchronization of the two motors through a synchronous controller unit.

Description

Technical field: [0001] The invention relates to a method for improving the speed synchronous control performance of a double-motor flexible coupling transmission system. Background technique: [0002] The permanent magnet synchronous motor has the advantages of simple structure, high efficiency, and high power density. In the transmission system of the factory, in order to make the transmission stable and meet the output power at the same time, a dual-motor or multi-motor drive mode is usually used. For the dual-motor control system, when one motor is disturbed by the load, the two motors in the transmission system will generate tracking errors. At this time, the dangerous situation of belt breakage may occur at the connection between the motors. Therefore, it is of great practical significance to study the speed synchronous control of the double permanent magnet motor system in the industrial automatic production line and high-power stable transmission occasions. At prese...
