以铝粉雾化生产过程中精分系统控制为对象,针对管道间的相互耦合干扰使管道风流量处于长期波动的状态而影响铝粉分级精度的问题,给出了一种铝粉精分系统管道风流量的先进控制策略.将PID控制优异的稳态特性和模糊控制良好的动态特性与暂态响应曲线的设定和协调控制相结合,提出了一种模糊PID协调控制策略实现精分系统管道风流量的控制,大大减小了回路之间的耦合干扰,克服了传统PID控制超调大、调节时间长等缺点.通过仿真验证,新型控制策略响应迅速、超调小、稳态特性好,取得了良好的控制效果.
Aiming at the problem of the fineness system control in the atomization process of aluminum powder and the disturbance of mutual coupling between the pipes, the air flow of the pipeline is in a state of long-term fluctuation, which affects the classification accuracy of the aluminum powder. An aluminum powder fineness system The advanced control strategy of pipeline wind flow.By combining the excellent steady state characteristics of PID control with the good dynamic characteristics of fuzzy control and the setting and coordination control of transient response curve, a fuzzy PID coordinated control strategy is proposed to realize the precision system The control of the duct air flow greatly reduces the coupling interference between the loops and overcomes the shortcomings of the traditional PID control such as overshoot and long adjustment time etc. The simulation results show that the new control strategy has the advantages of rapid response, small overshoot and good steady-state characteristics , Made a good control effect.
