斜坡演算法-
Based on optimal control theory and singularly perturbed theory, a singularly perturbed midcourse guidance law that guarantees air - to - ground missiles to ascent quickly is proposed. this new guidance law is a composite control law consisting of three parts : optimal climbing control using variable weighting factor method, minimum energy cruising phase control and minimum energy switching phase control. moreover, a new control logic is designed in order to remove influence of climbing control on switching phase. simulation results of a certain type of air - to - ground missile are presents. it is shown that, with simple control algorithm and feasible onboard implementation, this law not only guarantees air - to - ground missiles to ascent quickly, but also satisfies the requirements of midcourse phases. the studies have important theoretical meaning and great value of engineering application
