摘　　要：运用电机电气控制系统,结合冷连轧塑性变形原理,对带钢冷连轧机系统建立了稳态的数学模型。并用MATLAB/Simulink对冷连轧动态过程进行了数值模拟仿真。针对冷连轧控制系统中存在时滞、时变、大惯性、非线性等问题和传统PID控制器整定参数的局限性,提出了将模糊控制和传统PID控制结合在一起,构造成一个模糊PID控制器。最后通过数值模拟仿真实验证明:与传统PID控制器相比,模糊自适应PID控制器的动静态性能好,即响应时间短,超调量小,稳态性能好。Based on the electric motor control system and the principle of rolling plastic deformation,the stable state mathematical model of cold rolling process was established.The dynamic process of cold rolling was simulated by using the MATLAB/Simulink.Aimed at the problem of time-delay,time-varying,large inertia,nonlinear and others of cold rolling traditional PID control system,a new method combining a fuzzy control method and PID control method was put forward.By MATLAB simulating,results showed that static and dynamic performance of fuzzy adaptive PID controller was better than the traditional PID controller.The fuzzy adaptive PID controller had much more advantages,such as shorter response time,a smaller amount of overshoot,better steady-state performance.
