Study of Feedforward Problem for Bank-to-Turn Missile Autopilot Design

In course of missile autopilot designs,the fccdforward from the rudder deflection to the missile body overload variation adds an extra zero to the system and brings many difficulties,especially in modern control methods.So,the feedforward action is usually omitted artificially,which will cause quite large design error and even failure sometimes.How to solve the problem has not been seen in the open literature.With reference to bank-to-turn (BTT) missile autopilot design, a new method for solving fcedforward problem is presented here. For the pitch channels of BTT missiles, the method solves the problem by designing steady state compensation control laws and using low-pass filters to cancel the feedforward action. For the yaw channels, the method solves the problem by designing a 3-channel co-operating relation and redefining the system state variables, so that the autopilot design problem containing feedforward action are transformed into that containing none.The method proposed here is also suited to skid-to-turn missile autopilot design.Finally,simulation results are satisfactory.
