摘要
建立了串联双容水箱液位控制系统的数学模型,针对传统模糊控制存在静态误差较大的问题,提出了在模糊控制器上并联积分器,成功地消除静态误差。在PID算法的基础上提出了模糊PID算法。最后,对四种算法的系统性能进行了仿真比较,证明了带积分环节模糊控制系统具有良好的动态性能。
A mathematical model of a tow-capacity water tank level control system was established.Due to the fact that there is a big static error with traditional fuzzy control system,fuzzy controller in parallel with an integrator was proposed which successfully eliminated the static error.Based on the PID algorithm,fuzzy-PID control algorithm was proposed.At last,the system performance of the four algorithms was simulated and compared.The result proves the good dynamic performance of the one with integral fuzzy control system.
