The present disclosure relates to a multi-mover and multi-stator linear motor control system based on the quasi-longitudinal wave elasticity theory. The position sensor estimation module, the drive module and the current detection feedback module; the communication module obtains the position and velocity signals of the adjacent movers, and the position sensorless estimation module detects and estimates the current mover position and velocity. The safe position calculation algorithm of the multi-mover cooperative control module calculates the expected position of the current mover, and the quasi-longitudinal wave elastic theory control algorithm compares the expected position and the actual position of the mover, and solves the need to apply when the mover reaches the desired position. The electromagnetic force is further converted into current, and the current value obtained by the current detection feedback module is used as the feedback value of the current, and the high-precision control of the linear motor is realized through the drive module.
Description
technical field [0001] The present disclosure relates to the technical field of digital control systems, in particular to a multi-mover and multi-stator linear motor control system based on quasi-longitudinal wave elasticity theory. Background technique [0002] Linear motors (ie, linear motors) can directly generate linear motion, and can directly convert electrical energy into mechanical energy required for linear motion. Compared with the rotary motor, the linear motor has no mechanical contact, its transmission force is generated in the air gap, and there is no other friction except the linear motor guide rail; the running stroke is theoretically unlimited, and the performance will not be Affected by the change of stroke size; it can provide a wider range of operating speeds, especially at high speeds, its advantages are more prominent; in addition, linear motors also have the characteristics of large acceleration, stable operation, high precision and repeatability, and ...
