摘要
本文根据经典控制理论所导出的约束条件,采用基于二次型性能指标的线性最优调节器的方法,设计了飞行器滚动自动驾驶仪.分析和数字仿真表明,这种方法对于数学模型中的高频影响具有较好的鲁棒性.
The roll channel of a vehicle autopilot is designed in the light of opti-mal linear regulator with a quadratic performance index under the cons-traint conditions derived by means of classical control theory.Analysis and digital simulation show that this method has better robustness for high frequency effects in the dynamic model.
