A motion control system generally include: processing algorithms and motion signal to the controller; a signal enhancement, can supply actuator motor output amplifier; feedback (sensor / transmitter) system, based on the comparative value of input and output, adjust the process variables.
The system also includes an operator interface or a host terminal front-end equipment (front-end).Feedback means that most of the motion control system is a closed-loop system, but does not rule out some of the open loop system, especially the stepper motor system. Actuator in various forms - motor, a cylinder, a spiral coil, electrical, hydraulic, pneumatic or other types of equipment.
