摘要
根据物料守恒关系建立了管路压力的简化数学模型,针对传统PID算法适应性方面的不足以及蒸馏管路存在的进气干扰,提出对其管路压力采用自适应模糊PID控制算法,并利用前馈控制补偿进气口蒸汽的扰动。通过MATLAB对白酒蒸馏管路压力控制进行仿真研究,确定不同误差输入时的参数自整定规律。仿真结果表明,压力控制系统的静态和动态性能得到明显改善,响应时间快,超调量小,抗干扰能力强。
Mathematical model of pipeline pressure is built according to mass conservation.Aiming at solving the poor adaptability in routine PID algorithm and the disturbance of air inlet steam,adaptive fuzzy PID algorithm and Feed-forward controller are proposed in the control of pipeline pressure.System simulation is conducted by MATLAB,and parameter self-tuning rules under different errors are studied.Simulation results show that the pressure control system has better static and dynamic performance such as quicker response,smaller overshoot and better capacity of resisting disturbance.
