Finite-time attitude control for bank-to-turn missiles

The design of a continuous finite-time controller for bank-to-turn(BTT) missiles is considered in this work. The proposed controller allows that roll rate and angle of attack can track the desired commands in finite-time with sideslip angle maintained in a small degree range. Based on input/output(I/O) feedback linearizaiton technique and finite-time stability results for homogenous system, a continuous finite-time controller is proposed. Compared with asymptotically stable systems, finite-time stable systems offer better robustness and disturbance rejection properties. Computer simulation results are presented to validate the effectiveness of our method.
