Abstract
Traditional Integrated Flight/Fire Control (IFFC) system using the flight/fire coupler made the system functional uncoupling difficult. Based on the multi-strata hierarchical control theory, a new IFFC system of armed helicopter for air-to-ground gunnery mode was designed. It consisted of two level loops: the Space Pointing Track Loop and Tactical Mission Loop. In the first loop, two-degree-of-freedom (TDF) H∞ method was applied to realize the uncouple control of tree attitude channels of helicopter. In the second loop, the target state estimator and fire control algorithm were designed to provide the first loop with expected attitude pointing. The system discards the flight/fire coupler and decreases the coupling effect of the level loops. Simulation results show that the system can achieve the automatic tracking and aiming process with good performance and strong robustness in different target maneuvers. This design method can also be generalized to the fixed-wing IFFC system.
