Problems solved by technology
[0003] However, the inventors of the present invention have found in the course of research and practice that the processing platform using linear motors in the prior art still needs improvement, for example, when the control center suddenly appears If there is a calculation error or hardware failure, or there is a problem in the information transmission of a certain link (delay, data loss, etc.), then the entire processing platform will have control chaos; and when a certain mover has a physical connection failure, the mover Inevitable work failure, which affects the overall performance of the processing platform

The invention discloses a distributed type linear motor machining platform and a distributed type linear motor control method. The distributed type linear motor machining platform comprises a plurality of control systems, a plurality of linear motor systems and a guide rail type stator. Each linear motor system is connected with the corresponding control system. Each control system comprises a transceiver, a controller and a driver. Each linear motor system comprises a rotor, an execution mechanism and a sensor. All the linear motor systems share the guide rail type stator. The rotors move relatively along a guide rail of the guide rail type stator. Each linear motor system obtains self-movement information through the corresponding sensor and feeds the movement information back to the corresponding control system. The control systems are used for independently controlling the linear motor systems. By implementing the distributed type linear motor machining platform and the distributed type linear motor control method, the stability of the linear motor machining platform is improved, and the overall fault tolerance of the machining platform is improved.
Description
technical field [0001] The invention relates to the field of motor control, in particular to a distributed linear motor processing platform and a distributed linear motor control method. Background technique [0002] Due to the limitation of its own structure, the traditional "rotary motor + ball screw" feed transmission method on machine tools is difficult to make breakthrough improvements in feed speed, acceleration, and fast positioning accuracy, which cannot meet the needs of ultra-high-speed cutting. , Ultra-precision machining puts forward higher requirements for the servo performance of the machine tool feed system. Based on this, in the precision machining industry, people have introduced linear motors, which directly convert electrical energy into mechanical energy of linear motion, cancel the mechanical transmission link between the motor and the workbench, and shorten the length of the machine tool feed transmission chain to Zero, it is also possible to integrate...
