摘要
提出一种由带自调整函数的模糊控制器与二元函数的Lagrange插值算法相结合的控制算法,并将该算法应用于直流电机调速系统。详细论述和分析了该算法的实现过程和控制性能。自调整函数为指数函数,根据控制对象的具体情况和要求的不同,自调整函数中各参数可通过键盘进行调试。插值算法采用分片双二次Lagrange插值算法。在130SZK05型宽调速直流电动机上进行了调速实验,极大地改善了系统的控制品质和稳态品质。
A control algorithm combining the fuzzy controller with selfadjusting function and the binary function Lagrange interpolating algorithm was discussed. This algorithm is used in a DC motor speedregulating system. The realization process and control characteristics were discussed and analyzed in detail. The selfadjusting function is an index function. According to different instances and requests, the parameters in the selfadjusting function can be adjusted through the keyboard. The burst double Lagrange interpolating algorithm was adopted.A speedregulating experiment was made on a 130SZK05 wide speedregulating DC motor.Its control quality and steadystate quality are greatly improved.
