摘　　要：非线性系统广泛存在于各种实际问题中,但是建立复杂非线性被控对象的精确数学模型往往是很困难的,对非线性系统实现稳定控制是过程控制工程中的一项困难的课题。无模型控制方法是以非线性途径设计出来的,因而用它来控制某些非线性复杂对象时,表现出了它的优良控制品质。主要说明了无模型控制方法实现了智能推理算法化,不同于一般的智能控制算法,同时分析了无模型控制律对非线性被控对象收敛的快速性,通过具体的工程实例说明了无模型控制方法在非线性系统中的成功应用。Nonlinear systems are widespread in the various practical problems, but it is very difficult to build the accurale mathematical model of complex nonlinear objects. To achieve the stability control for nonlinear systems is a difficult task of control engineering. The model free control method is designed by nonlinear approach, so it can show its good quality to control some nonlinear complex objects. This method has achieved an intelligent reasoning of the algorithm, so it is different from the general intelligent control algorithms. The rapid convergence of the model free control law for nonlinear controlled objecets is analyzed. Specific engineering examples show the successful application of model free control method for nonlinear systems.
