摘　　要：针对目前城市二次供水恒压控制系统中存在非线性与滞后、间歇性扰动等带来的高层用户用水欠稳问题,建立供水数学模型,将模糊和天牛须优化算法分别引入到恒压供水PID控制算法中,分别设计了模糊和天牛须优化算法的Matlab程序和控制模型并进行仿真数据对比分析。仿真对比结果表明,相较于传统PID算法,模糊PID算法的抗干扰波动小,天牛须PID算法的超调量和调节时间更小,两者均较传统PID算法有更大的优势。This paper aims at the constant pressure control system that has non-linearity,hysteresis,intermittent disturbance,which brings high-level users to the problem of unstable water pressure,and established a mathematical model of water supply.The Fuzzy Logic Control and BAS algorithms are applied into regular PID control of constant pressure water supply system.The MATLAB program and control model of fuzzy logic control and BAS algorithms are designed respectively.The results show that compared with the traditional PID algorithm,the anti-interference fluctuation of fuzzy PID algorithm is small,and the overshoot and the adjustment time of the BAS-PID algorithm are smaller.Both Fuzzy-PID and BAS-PID optimization algorithms have greater advantages than the traditional PID algorithm.
