摘　　要：通过分析基本无模型控制律对复杂被控系统进行控制时存在的不足,说明了无模型控制律中包含功能组合部分的必要性。进而介绍了功能组合部分的构成,讨论了无模型控制律中增加的功能组合部分的功能和作用。采用系统仿真的方法对完善后的无模型控制律的收敛性、适应性、克服大时滞能力及解耦能力等性能进行了分析,并介绍了完善后的无模型控制律在实际应用中的两个应用效果的例子。结果表明,功能组合部分的增加,提高了无模型控制律的收敛性、适应性、克服大时滞能力及解耦能力等性能。The drawback that the complicated systems are controlled by the basic model free control law is analyzed. The necessity of functional combination part of model free control law is explained. The constitution of the functional combination part of model free control law is introduced. The effect of the functional combination part of model free control law is discussed. The properties of perfect model free control law, such as convergence, adaptive, recovering large scale time-delay and decoupling, are analyzed with simulation method. Two examples of application effect in the practical industry show that the functional combination part improves the properties of convergence, adaptive, recovering large scale time-delay and decoupling.
