摘　　要：电厂单元机组负荷系统是一个有强烈耦合的多变量对象。本文提出的方法以多变量内模控制为核心,将基于支持向量回归的在线辨识算法引入到多变量内模控制的设计之中,从而形成了一种新的解耦控制策略。仿真结果表明,该方法使得机组负荷具有良好的跟踪性能,在对象动态特性较大范围内变化的情况下,系统具有较强的鲁棒性。The thermal power unit load system is an object with strong coupling. The proposed method is based on multivariable IMC, which introduces online identification algorithm, based on support vector machine, into the structure design of multivariable IMC, and then formed a novel decoupling control tragedy. The simulation results show that the system has good tracking property and strong robust performance while dynamic property of the controlled plant varies in a wide range.
