Research on the Automatic Control System of Light and Small Ground Holding Poles Based on Embedded Technology
On the basis of analyzing the structure of light and small ground holding poles,a framework for the auto-matic control system of light and small ground holding poles based on embedded technology is designed.After the basic data unit collects the operating data of the light and small ground holding poles,the embedded main controller of the control unit calls the variable frequency speed control program to control the operating speed of the lifting motor.The hook load torque compensation control is achieved through a fuzzy PID controller,and use particle swarm optimization algorithm to perform online real-time tuning of controller parameters,issue control instructions to various working mechanisms through CAN bus,and use Ethernet to achieve information exchange with remote control centers.The experimental results show that the system can achieve automatic control of light and small ground holding poles,with smooth step response curves,low overshoot,short control time,stable and smooth output analog voltage curves,and no oscillation problems.
