摘要
针对大惯性、纯迟延、非线性、时变的黏胶剂生产过程,提出一种模糊免疫PID控制算法,该算法根据模糊控制原理对PID参数模型中的kp、ki、kd进行在线修改,利用生物免疫机理调整非线性函数,然后用免疫修正进一步调整PID系统参数,较好地实现了反应釜温度的跟踪控制。仿真结果表明,该算法具有一定的较常规的PID控制算法优越性。
Aiming at the characteristics of adhesive preparation process （lengthy, nonlinear, time-varying, big inertia and pure delay）, Proportional-Integral-Derivative （PID） algorithm was propesed,in which the main parameters including kp,k1,and kd were adjusted on line,according to the fuzzy control rules. Nonlinear function was adjusted by using biologic immunity mechanism, Then, the system parameters of PID were further tuned by immune regulation, thus, the temperature of polymerizing-kettle could be tracked and controlled. The simulation results verified the effectiveness and superiority of the control algorithm.
