Adaptive Attitude Takeover Control for Spacecraft with Input Quantization and Saturation

摘要

The attitude takeover control problem of multi-cellular satellite spacecraft with quantized drive torque and input saturation is studied. In order to reduce the communication burden between the control cell satellite and the actuator cell satellite, hysteresis quantizer is used for the control torque signal. An adaptive inversion control scheme is proposed to solve the attitude takeover control problem. The auxiliary system and Nussbaum function are introduced in the control scheme to extend the attitude dynamic system to the state of the augmented system under the influence of input saturation and adjust the dynamic gain of the internal controller. Simulation results verify the effectiveness of the control scheme.
