提出引入σ校正技术的复合模型参考自适应控制方法，可以克服已知的系统干扰。存在未建模动态和未知干扰时，在任何有界的初始条件下，σ校正复合模型参考自适应控制系统的跟踪误差都是有界的。针对典型的汽包锅炉汽轮机系统的非线性模型，将静态状态反馈精确线性化方法和σ校正复合模型参考自适应控制方法相结合，设计了协调控制器。讨论了静态全状态反馈线性化对多输入多输出系统的干扰抑制能力和对多输入多输出摄动系统的鲁棒线性化问题。介绍了非线性σ校正复合模型参考自适应控制器的设计方法。给出了满足约束条件前提下的模型匹配条件的极点配置设计方法。仿真结果表明，所设计的复合控制系统可以实现良好的解耦控制，鲁棒性和抗干扰能力强。

This study introduced the σ-modification approach into a composite model reference adaptive control system, which could overcome the known systematic disturbance. The tracking error of the σ-modification composite model reference adaptive control system is bounded under any bounded initial conditions in the presence of unmodelled dynamics and unknown interference. A coordinated controller was designed by combining the static-state feedback exact linearization method with theσ-modification composite model reference adaptive control strategy based on the typical nonlinear model of the drum-type boiler-turbine system. The disturbance rejection problem for multi-input multi-output (MIMO) system and the robust linearization problem for the MIMO perturbed system of the static full state feedback exact linearization method were discussed. The design method of the nonlinear σ-modification composite model reference adaptive controller was expounded. The pole placement design scheme of the model matching condition was given under the premise of meeting constraint conditions. The simulation results show that the designed combined control system can achieve excellent decoupling control, robustness and disturbance rejection ability.
