A system and method is provided for thruster control in a flight vehicle. The system and method uses a proportional derivative matrix control technique to determine thrust commands in a Divert and Attitude control (DAC) system. The proportional derivative matrix control system is configured to receive pitch, roll and yaw commands as inputs, and generate thrust commands as outputs. The performance of the proportional derivative matrix controller is such that the thrust commands can achieve the desired attitude angles quickly and with reduced fuel consumpt...
1. A thruster control system for a flight vehicle comprising: only four thrusters that provide pitch, yaw and roll control; anda processor configured to receive pitch, yaw and roll commands, and responsive to the pitch, yaw and roll commands generate a plurality of thruster commands in a thrust command matrix T for the four thrusters using a matrix control technique, said processor calculating T=[B]−1 M where M is a vehicle moment matrix, B is a coupling matrix that defines a relationship between a thrust provided by the thrusters and a plurality of mome...
