调压系统模糊控制器的回归分析模型设计

Fuzzy Controller of Voltage Regulator System Regression Analysis Model Design

电压调节系统常采用PID调节,其控制调节时间较长且超调量大.通过对该系统的分析,设计出满足其控制效果的模糊控制器,从而实现系统的模糊控制.考虑回归分析模型是确定的数学函数关系式,只需进行加减法与乘除法运算,在微机如PLC中有相应的指令,很容易通过编程来实现.仿真表明,其控制效果与模糊控制器控制效果吻合.

Voltage regulating systems often uses PID regulation which requires long time to control and has large overshoot.Based on the analysis of the system,a kind of effective fuzzy controller was designed.Since the regression analysis model is determined by the mathematical function relationship,it is enough to make addition and subtraction,multiplication and division operations,so it can easily be programmed to achieve in microcomputers such as PLC instruction.Through the simulation,the control effect of regression analysis model and fuzzy controller model is basically consistent.
