Summary :
|
THIS WORK DESCRIBES THE STRATEGY OF COUPLING COMPENSATION OF THE CONTROL SYSTEM OF A ROTATIVE MISSILE. THE CONTROL SYSTEM USES ONLY ONE PLAN OF ACTUATION AND ONE RATE GYRO THAT COMPARES WITH THE ANGULAR SPEED COMMANDED BY THE GUIDANCE SYSTEM. DUE TO THE COUPLING CAUSED BY THE HIGH ROTATION OF THE MISSILE, THE MEAN ANGULAR RATE OF THE VEHICLE IS NOT PLACED IN THE SENSOR PLAN WHERE IT WAS MADE THE MEASUREMENT. TO SOLVE THIS PROBLEM A STRATEGY OF MECHANICAL PHASE LEAD IS USED, THAT IS TO SAY, THE SENSOR PLAN IS DIFFERENT OF THE PLAN OF ACTUATION IN SUCH A WAY IS PLACED THAT THE MEAN MOVEMENT MEETS INSIDE OF THE SENSOR PLAN, FROM WHERE THE COMMAND ORDER WAS ELABORATED. TO OBTAIN THE VALUE OF THE ANGLE BETWEEN THE SENSITIVE AXIS OF THE GYRO AND THE PLAN OF THE ACTUATORS, A VECTORIAL TRANSFER FUNCTION IS USED. |
