SYNTHESIS OF THE PITCH AUTO-PILOT SYNTHESIS IN MISSILES WITH PARTICULARLY UNSTEADY DYNAMIC PARAMETERS
Danilo Čuk Slobodan Mandić
A procedure of the pitch autopilot synthesis in missiles with particularly unsteady dynamic parameters including also the possibility of aerodynamic configuration static unstability has been presented. Two variants have been treated: with and without synthetic feedback along the angular pitch rate. Besides the missile dynamic derivatives as functions of time, the input data for the synthesis are the autopilot requested characteristics: time constant of aperiodic time lag, relative damping factor and cutoff frequency of open circuit amplification. The verification of amplification factors determined by the synthesis has been carried out by the numerical simulation of the autopilot at different instants for different flight altitudes.
