摘要
应用Ｈ∞控制的Ｓ／Ｔ混合灵敏度方法于船舶自动舵设计。按机理估算模型乘性摄动上限，据此确定优化指标中的权函数Ｗ２。利用设计的控制器对闭环系统在多种环境条件下进行了仿真研究，结果是满意的。
he weighted mixed sensitivity optimization approach of H∞ control theory is applied to the design of an autopilot for ships. Physical consideration in selecting the weighting matrix W2is emphasized. The controller obtained is tested by simulations showing satisfactory performances under changing environment conditions and model perturbations caused by speed and load variations.
