In order to improve the accuracy of two-dimensional trajectory correction and ensure the realtime performance and reliability of the correction mechanism,this paper designs a controller based on DSP and STM32 two-dimensional trajectory correction dualcore control system to process and calculate the information in real time to ensure the trajectory correction control function realization.Firstly,the overall structure and key functional modules of the controller are introduced in detail,and the software design is carried out according to the control system workflow.The UKF is used to process the ballistic data to improve the accuracy of data measurement,and then the correction mechanism is controlled by neural network PID to improve the realtime performance of the system.Finally,it is verified through experimental simulation,and the results show that the control system can meet the design requirements of the system.
