Integrated guidance and control for precision guided munition for anti-tank application

For the case of precision guided munition against tanks a scheme of Integrated Guidance and Autopilot design has been studied. The three dimensional interception problem has been resolved in to two orthogonal two dimensional interception problems; the two orthogonal planes being the pitch and yaw plane. Using integrated guidance and missile autopilot system a sliding mode controller has been implemented in each plane. The sliding mode controller uses zero effort miss as the sliding surface. The performance of the system was analyzed using numerical simulation and the moving target (tank) was hit successfully. Perturbation studies were performed by injecting noise into the different measurements. The interception scenario was not altered, thus proving the robustness of the control law.
