A Guidance Function Model Based on Target Motion Equation
In the tracking,aiming and performance test of large inertia weapon system,the guidance control of fire control system plays an important role in achieving smooth gun adjustment.Limitations of the traditional guidance function with various forms and complex calculation were analyzed and a new guidance function model was proposed.Based on the polynomial with parameters,the system attitude angle function,the target motion angle function and the guidance time were considered in the model.The angular position,angular velocity and angular acceleration should have no sudden change in con-nection with the system attitude angle at the beginning of guidance,and have no sudden change in con-nection with the target motion angle at the end of guidance.Based on this condition,the model para-meters were solved and the guidance function form was determined.The guidance effect under four dif-ferent guidance requirements,including angle static rotation,target tracking,target dynamic switching and sinusoidal periodic motion was given by simulation.The simulation results show that signals of the guidance function well realize the smooth connection of the angular position,angular velocity and angu-lar acceleration,and provide an effective method for the guidance control during the tracking,aiming and performance test of the large inertia weapon system.
