摘要
首先对变频泵控调速系统进行理论分析,建立了系统的数学模型。针对系统的非线性、变负载等特性,利用模糊PID作为系统的控制方案,设计模糊PID控制器。最后运用Matlab分别对系统的常规PID控制和模糊PID控制进行仿真,对其效果进行验证。
Firstly, the mathematical model of the variable - frequency - pump - control speed governing system is established by the paper. For the system of nonlinear, variable loads and other characteristics,the fuzzy - PID is used by the system, and then design the fuzzy- PID controller. Finally, using the Matlab to prove the effect of fuzzy - PID.
