Paper Abstract

Based on the model of gyro-stabilized platform which is a nonlinear system with high dimensions, an approach to robust control design for a multi-input/multi-output (MIMO) plant using eigenstructure assignment (EA) and quantitative feedback theory (QFT) is introduced. EA is used to decomposition of the MIMO system into decoupled SISO subsystems. Then the SISO QFT technique may be used to obtain robust stability under the given plant-parameter uncertainties. The simulation shows that the combined EA/QFT approach provides a more straightforward physical understanding of the design process and gives designers greater flexibility in making tradeoffs between system performance and controller complexity, and also shows that target tracking system has the good decoupling performance and high tracking precision even though space vehicle makes acute maneuver.
