Control technique research on vertically launched missiles based on variable structure control

The problem of vertical launch of missiles is discussed in the paper. Firstly, the model of the missile with an integrated aerofin/thrust vector control is proposed, and subsequently linearized. Secondly, a proportional guidance law using virtual target is introduced, and variable structure controllers of three channels are designed based on the linearization model. Lastly, the study of a 6DOF trajectory simulation validates the correctness and effectiveness of the designed guidance law and three variable structure controllers.
