【摘要】 本文提出了一种新型的不依赖专家经验知识建立系统控制器语言模糊规则基的方法,即仅根据系统的输入输出特性来构建系统模糊控制器的规则基.在对传统进化规划算法改进的基础上,巧妙地将其与PID控制技术相结合,既克服了PID控制器三大参数(比例、积分、微分)往往依赖一些近似的整定方法来求取的弱点,同时又充分发挥了进化计算强大的数据挖掘功能,实现参数非线性PID控制.通过对交流伺服系统的仿真,证明了该方法具有很强的实用价值,值得进一步研究.更多还原

【Abstract】 A new method, which is not depend on knowledge of experts, of setting up rule bases of system′s controller is proposed, namely, it is dependent on the characteristic of the input and output.The conventional evolutionary programming is also improved. The combination of evolutionary programming and PID control overcome the disadvantage of determining parameter of PID controller which dependent on approximately methods.Moreover,the digging digital ability of evolutionary-programming is used and nonlinear PID is realized.The simulation of AC servo system indicates the practical value of the given method.更多还原
