Research on Electric Servo Control System of Unmanned Boat
In order to solve the problems of slow dynamic response speed,insufficient control accuracy and low reliability of existing electric servo system of unmanned ship,an unmanned boat electric servo control system based on position closed-loop feedback control is proposed considering the characteristics of the position loop,speed loop and current loop controllers,and speed loop and current loop are added to further optimize the servo control algorithm.The system realizes various functions such as system initialization,closed-loop control algorithm,PWM signal generation,serial communication,etc.It is constructed into a servo control system from both hardware and software aspects.The test results show that the proposed position loop closed-loop feedback control system meets the requirements of the unmanned ship electric servo in terms of stability,response speed,control accuracy,and the controllers of the added speed loop and current loop enhance the dynamic response and tracking performance of the servo control system,which provides a valuable reference for expanding the application range of the electric servo in the field of the unmanned ship.
