摘　　要：针对研究无模型控制律的收敛性问题,通过对无模型控制律基本形式的收敛性进行了分析,得到无模型控制律一般形式的收敛性定理,证明了在无模型控制律作用下,系统的输出将收敛到任意给定的希望输出值。应用实践表明,该控制律明显优于PID调节律,某些用PID调节器尚不能实现闭环控制的被控环节,应用依据该控制律设计的无模型控制器后,都实现了闭环稳定控制。Aiming at the problem of the convergence of the model free controller, based on the analysis of the convergence of the basic form of the model free controller, the convergence theorem is achieved. It has been proved that the output of the system under the action of the model free controller converge to any given expected output value. Application practices have shown that the model free controller is much better than PID regulator and a steady closed-loop control can be achieved by using the model free controller for some controlled sectors for which the closed-loop control can not be achieved by using PID regulator
