Abstract EN
To minimize the cost and maximize the ease of use, a class of dual-spin mortars is designed which only rely on GPS receiver and geomagnetic measurements.
However, there are some problems to be solved when the range is small, such as low correction authority and trajectory bending.
Guidance law design for this mortar is detailed.
Different guidance laws were designed for the ascending and descending segments, respectively.
By taking variable parameter guidance law in the vertical plane and using compensation in the lateral plane, the problems mentioned above were resolved.
Roll angle resolving algorithms with geomagnetic measurements were demonstrated and the experiment results proved to be effective.
In order to verify the effectiveness, Seven-Degrees-of-Freedom (7-DOF) rigid ballistic model were established and hardware in the loop simulation was introduced.
After the transform function of the actuator was obtained, the control model of the shell was improved.
The results of the Monte Carlo simulation demonstrate that the guidance law is suitable and the mortar can be effectively controlled.
