摘　　要：无模型控制方法在实际应用中收到了良好的效果,因为其具有适应性、抗干扰能力、解耦性能和强制稳定能力等一系列优秀的性能。从理论上对这些性能进行分析十分必要,但比较困难,因此,介绍对无模型控制方法某些重要性能通过仿真分析的结果。因为目前在工业过程控制中所应用的控制器90%以上是PID调节器,所以仿真采用了与PID调节器相应性能进行比较分析的途径。仿真结果说明了无模型控制方法在适应性、抗干扰能力、解耦性能和强制稳定能力等方面都强于PID调节器。另外,对所设计的仿真系统进行了简单的介绍。Model-free control method is discussed, which has received good results in the practical application because of excellent performance, such as adaptability, anti-jamming capability, decoupling performance, mandatory stability, etc. To the necessity and difficulty of the theory analysis of these performances, the simulation results of some important performances of model-free control method are introduced. Because more than 90 percents of controllers used in industrial process control are PID regulators, the simulation is done to compare the corresponding performances of PID regulators. Simulation results show that the model-free control method is better than PID regulator in adaptability, anti-jamming capability, decoupling performance, mandatory stability. The designed simulation system is simply introduced.
