Automatic feeding control system for fish

Based on Nios II embedded processor control module, a digital control system was designed for wire feeding control of gas tungsten arc welding(GTAW). In the control system FPGA wave module is used to control the movement of the DC servo motor, and the digital control of pulsed wire feeder for GTAW was achieved. One and the same control module with Nios II embedded processor is used to control the wire feeder and the welding power source. Thus, the current parameter of pulsed welding arc can be obtained and used directly for controlling the speed of wire feeding. At last, the experiment results are provided to verify the validity.

This paper proposed a CAN-bus and stepper motor based yarn feeding control system for tufting carpet machine. Base on requirement of yarn feeding devise control system architecture. Control system adopts the industrial computer as the master platform and user interface, the lower computer consists of yarn feed step motor controller, speed synchrony controller and yarn guiding controller. Design the communication protocol and the control logic. Through establishing control system prototype system to verify the system function, test results show that the design scheme is feasible
