Summary: | The invention discloses a linear pseudo spectrum distribution control guidance method with fall angle constraint. The method comprises the steps that firstly, a set of weight sums of standard basis functions with undetermined coefficients are used for expressing control variables; then, through an Eulerian method, a system state equation is subjected to linear processing to obtain a linear optimalcontrol problem; and a Gaussian pseudo spectrum method and a model prediction control theory are used for converting the linear optimal control problem into solution of a system of linear equations so as to obtain a corrected control quantity meeting the fall angle constraint. The linear pseudo spectrum distribution control guidance method with the fall angle constraint can meet the off-target quantity and terminal fall angle constraint, and energy control in flight process is optimized. According to the method, solution is performed based on a linear pseudo spectrum distribution control guidance law, the same calcul |
