恒压供水系统模型为带有滞后环节的一阶惯性系统,系统参数会随着外部环境影响而变化,因此常规PID控制算法达不到很好的控制效果.针对这种情况,采用模糊PID控制算法,通过在PID算法的前端引入模糊控制算法,实时在线调节PID算法中的比例系数、积分系数和微分系数.MATLAB仿真结果表明,与常规PID控制算法相比,采用模糊PID控制算法具有响应速度快、超调量低、稳定性好的优点.
Abstract：The model of constant pressure water supply system is a first-order inertia system with hysteresis, and the system parameters can change with the influence of the external environment, so the conventional PID control algorithm cannotachieve the good control effect. In view of this situation, the fuzzy PID control algorithm was proposed,and the fuzzy control algorithm was introduced in the front of the PID algorithm, and the proportion coefficient, integral coefficient and differential coefficient of the PID algorithm were adjusted in real time. MATLAB simulation results showed that the fuzzy PID control algorithm enjoys the advantages of fast response, low overshoot and better stability compared with conventional PID algorithm.
