| description | The invention discloses a positioning vehicle multi-transmission master-slave device control method, which is characterized in that a plurality of frequency converters are connected with a PLC (Programmable Logic Controller) through a first bus, the plurality of frequency converters are connected through a second bus, the PLC sets any one frequency converter as a master frequency converter through the first bus, and the other frequency converters are set as slave frequency converters through the second bus; in the control process, all the frequency converters share a main frequency converter ramp function generator to calculate an RFG output set value, a Droop softening function is adopted for main and slave load control, and meanwhile, a method of adjusting an integral set value of a slave frequency converter speed regulator by adopting an integral element torque set value of a main frequency converter speed regulator is adopted. And dynamic load balance of the master and slave devices is realized. According |
