For intercepting the hypersonic target head on, the velocity of the hypersonic target interceptor besides angle, and attitude, are the key points at hand-over time. Trajectory optimization is a practical method to provide satisfied states for the interceptor. To decrease the large relative velocity at the hand-over time, and satisfy the angle and attitude constraints, this paper presented the hp-adaptive...
For the air-breathing hypersonic missile with low overload in cruise phase due to angle of attack restriction, an aerodynamic force and lateral thrust blended control autopilot is designed, which based on fuzzy control theory. The non-linear system model in the longitudinal plane of a hypersonic missile is built, and several fuzzy control strategies are applied in overload command allocation, so as...
A novel adaptive neural network dynamic surface control is proposed for hypersonic vehicle. Based on the hypersonic vehicle model characteristics, the adaptive neural network dynamic surface control attitude controller and the neural networks velocity controller are designed, respectively. By combining Nussbaum gain function with decoupled backstepping, the problems of unknown control directions and...
A novel guidance law based on extended quadratic cost function is proposed to avoid losing performance index, which is commonly appeared when using cost function with quadratic form. Stochastic optimal guidance laws under target maneuver and target non-maneuver conditions are deducted and are validated by simulating in turn. The simulation results show that guidance trajectories based on extended...
The comparison principle for general continuous time nonlinear Markov jump system is established. Later, using the comparison principle, we obtain some stability criterion, including stability in probability, uniformly stability in probability, asymptotic stability in probability, uniformly asymptotic stability in probability, pth moment stability, pth moment uniformly stability, pth moment asymptotic...
Classifying the jamming of guidance system and inducing its characteristics; and the importance of jamming and anti-jamming in the missile guidance are analyzed. In order to make the missile dive target with higher speed and attack it in the limited time, designing Kalman filter based on missile and target relative movement modeling; researching the anti-jamming abilities and techniques. The result...
Based on multisensor information fusion theory and optimal control theory of structure stochastic jump system, a new guidance law is proposed for air-to-air missiles based on information fusion of active radar and infrared sensor, and its validity is testified by analysis on simulation by building digital model of missiles. Compared with proportion navigation law and extended proportion navigation...
