| 摘 要： | 高压超临界萃取控制参数具有时变、非线性的特点,对其进行精确控制具有很大难度.PID控制广泛应用于工业过程控制,但常规PID控制器参数对运行工况的适应性差.模糊控制具有不依赖系统数学模型、调节速度快、鲁棒性好等优点,但稳态精度欠佳.将PID控制与模糊控制相结合,设计了模糊PID反馈控制器,形成了模糊PID复合控制方法.以...

| Abstract: | The accuracy control problem of high press supercritical extraction process with the time-variant and nonlinear controlling parameters is discussed,The PID control is widely used in industrial process control,but the compatibility of normal PID control method is not well.The fuzzy control is independent on mathematical model and possesses rapid regulating speed and good robustness,but its homeostatic accuracy is not excellent.,The fuzzy-PID controller is designed based on the PID control and fuzzy control m... |
