延迟系统的一种模糊增量控制方法及应用

对于大滞后对象,传统模糊控制器的控制效果并不理想。该文在延迟系统逆动力学过程定性分析的基础上,对传统模糊控制器加以改造,提出一种新的适合于迟延系统的控制方法。以控制历史数据为基础,对控制量定义了新的矫正基准参量,设计了一种模糊增量型控制器。与传统的模糊控制器相比,该控制器能够综合反映历史控制对当前控制效果的影响。仿真结果表明,该控制方法可以明显地改善迟延对象的控制效果,并具有较强的适应性。

A Fuzzy Increment Control Method of Delay System and Its Application

To the large time-delay system,the control result of conventional fuzzy controller can not be satisfied.Based on the qualitative analysis to inverse dynamics of delay system,through modifying conventional fuzzy controller,a new control method which is fit for delay system is presented.Based on history control data,and defined new rectifiable norm parameter on control parameter,a fuzzy increment controller is designed.Compared with conventional fuzzy controller,this controller can synthetically reflect the history control's affection on the current control effect.Simulation result shows that this control method can evidently improve the control effect of time-delay system,and has stronger adaptability.
