In order to obtain better guidance performance, a dual-control sliding mode guidance rate of proportional guidance + flight speed control in three-dimensional space was proposed for a class of missiles with flow-adjustable engines, using the increased freedom of flight speed control. On the basis of proportional guidance, on the basis of two-dimensional and three-dimensional zero-control miss distance analysis, the suitable sliding mode surface is selected with zero controlled miss distance as the tracking target, and the uncertainties in the sliding mode surface are estimated by using the auxiliary sliding mode surface and the finite-time super-twisting interference observer. The simulation results show that, compared with the classical proportional guidance, the designed guidance rate miss is smaller, the trajectory is smoother, and the active control of the missile flight speed is realized under the consideration of air resistance.
