Embodiment Construction

[0039] The present invention is further described below in conjunction with accompanying drawing:

[0040] see Figure 1 to Figure 4 , the present invention uses a fault-tolerant control system to control three parallel DC motors, and at the same time, the system includes a reference current calculation module and a current reconstruction calculation module to convert three current signals into four current signals. During the working process of the motor, according to the collected instantaneous signal x i i=(1.2.3) At the same time of current reconstruction calculation, the fault detection and fault-tolerant control technology is used to detect the electrodes in the process of real-time operation, so as to ensure the normal operation of the three-parallel DC motor.

[0041] see figure 1 , the fault-tolerant control technology of the parallel system of three DC motors in the present invention mainly includes a three-parallel DC motor, a position sensor, a speed calculation...

Abstract

The invention discloses a three-DC motor parallel fault-tolerant control system and control method. At the same time, the system includes a reference current calculation module and a current reconstruction calculation module to change three-way current signals into four-way current signals. During the working process of the motor, while the current reconstruction calculation is performed according to the collected instantaneous signal, the fault detection and fault-tolerant control technology is used to detect the electrodes in the real-time working process to ensure the normal operation of the three-parallel DC motor; The fault-tolerant control technology of the DC motor parallel system is relatively simple to implement. It can effectively realize the related control of the three-parallel DC motor and at the same time ensure the normal operation of the motor. The operation is less difficult and easy to understand.

Description

technical field [0001] The invention belongs to the technical field of motor systems and controls, and in particular relates to a parallel fault-tolerant control system and control method for three DC motors. Background technique [0002] In the current development process, the three-DC motor control system has very important research significance, and has a very wide range of applications in daily life, which has attracted the attention and attention of more and more researchers. However, based on the characteristics of the three-DC motor itself when it is working, its use environment is complex. Under such circumstances, various unexpected problems often occur during the operation process, which brings many difficulties to the normal operation. Problems and difficulties, on the one hand, cause irreversible damage to the performance of the equipment, and on the other hand, may cause various dangers and accidents. Contents of the invention [0003] The object of the prese...
