Multi-Motor Synchronous Control System for Self-Driving Articulated Arm Measuring Machine
To solve the problem of multi-motor synchronous rotation of self-driven articulated arm measuring machine,a set of multi-motor synchronous control system is designed.The DSP processor with TMS320F28335 as the core is selected by the control system.And the driver board interface circuits,such as dual CAN communication circuit,power inverter circuit,motor drive cir-cuit,are designed orderly.Then,the simulation model of multi-motor synchronous control is established by Simulink.The above motor control model is converted into engineering code.Accordingly,point-to-point position synchronization experiments with different position angles set for six motors are performed,as well as multi-motor trajectory tracking experiments.Experimental re-sults show that the synchronous control time accuracy is within 10ms,which can not only verifies the synchronous control effec-tiveness of the six motors,but also provide references for improvement of motion stability and measuring efficiency of measuring machine.
