Velocity-constrained trajectory planning of anti-ship missile

Aiming at the velocity-constrained trajectory planning problem, a strategy to find the optimal reference trajectory is proposed. The given strategy is a combination of the well-known direct shooting method and the interior point method, such that a continuous optimal control problem is transformed into a finite dimensional nonlinear programming problem through the direct shooting method, and then we could utilize the interior point method to solve the corresponding problem. The optimization goal in this paper is to minimize the control input along the trajectory. The numerical simulations are provided to demonstrate our strategy. Moreover, it is shown that the imaging of seeker is also guaranteed.
