【Abstract】 In view of the influence of navigation environment and ship operation on ship navigation at sea, The control error of the navigation direction and the navigation speed of the ship is increased, In order to improve the automatic control accuracy of ship navigation, The design of navigation automation control system based on DSP technology is proposed. In terms of hardware design, The reset circuit and peripheral interface circuit are designed by using DSP technology, and the automatic control circuit of ship navigation is designed. According to the working principle of ship navigation automation controller, Complete the design of ship navigation automation controller, Using the error function of ship navigation automation control, In the descending direction of the function, the weights and thresholds of automatic control are adaptively adjusted, The network model of ship navigation automatic control is established, Combined with the automatic control flow of ship navigation, Complete the system software design, Realize the automatic control of ship navigation. The experimental results show that, The navigation automation control system based on DSP technology can not only reduce the control error of ship navigation direction, The speed control error can also be reduced, Thereby improving the control accuracy of ship navigation.更多还原
