摘要
针对水轮机调节系统的特性，设计了一种ＰＩ型模糊控制器；并根据偏差和偏差变化率的相平面图，建立了调节系统的动态特性和规则基之间的定性关系，避免了规则基设计过程中过多的依赖于主观因素的影响，使规则基的设计更趋于合理。仿真结果表明，这种模糊控制器在有功功率自动调节时，可以较好的克服“水锤效应”的影响，具有较好的动态品质。
?For the characteristic of hydraulic turbine requlation system, designed a PI-type fuzzy contronller; Based on the phase-plane of the error and the derivative of error, constructed the special relationships beteen the dynamic behaviour and the rule-base, reduced the subjective influence in the rule-base designing process, made the building of the fuzzy controller more easy and more reasonable. The simulation results showed, the proposed method can satisfying solve the control problem of the hudralic turbine requlating system and is feasible.
