摘　　要：针对变比值系统PID控制器参数整定复杂、调试时间长及对被控对象适应性差的特点,设计了基于模糊调节的变比值控制系统,利用过程控制系统Simulink工具箱SimProcess Toolbox中的过程动态特性模型库、控制与执行器库,设计了模糊调节变比值过程控制系统。仿真结果表明模糊调节比值器简明、有效,模糊调节的变比值控制系统不仅动态过程调节性能好,而且控制器参数整定简单,对过程对象的变化适应性强。Process system PID controller parameter tuning is difficult to adapt to the adjustable ratio process control system and weak adaptability for the controlled objects.To improve control stability and dynamic response,an application of ratio process control system based on fuzzy logic with SimProcess toolbox was realized.The result of simulation indicates that the fuzzy adjust ratio process control system has the characteristics of static accuracy good dynamic response and adaptability.
