双容水箱液位模糊串级控制系统的设计

模糊PID控制结合了PID控制算法和模糊控制方法的优点,可以在线实现PID参数的调整,使控制系统的响应速度快,超调量减少,振荡次数少,具有较强的稳定性。论文先对双容水箱进行数学建模,将模糊控制和PID控制相结合,设计出了双容水箱液位模糊PID串级控制系统。然后参照经验选取了合适的模糊控制规则和隶属度函数,设计了模糊控制器,建立了模糊控制表,供在线模糊控制查询使用。

Liquid Misty String Class Control System of Design for Double Water Tank

The misty PID control combined PID to control calculate way and fainmess to control the advantage of method, the speed that can be on hne to carry out the adjustment of PID parameter, make to control responding to of system was quick, super adjust quantity de crease, flap to concuss number of times little, have a stronger stability. This text permits water tank to carry on mathematics model to the double first and combines together misty control and PID control and designed the double permit a water tank liquid misty PID string class control system. Then according to experience to select by examinations accommodation of misty control rule with belong to one degree function, designed misty controller, build up misty control form, provide the on-line misty control the search use.
