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...
