摘要
传统PID对收卷张力系统控制时会造成PID控制器的积分积累,致使控制量超过允许的极限控制量,引起系统较大的超调,甚至是系统振荡,这在生产中是绝对不允许的。为此将积分分离PID控制算法应用于PLC对收卷张力进行控制。与传统的PID控制算法进行比较该算法改善了控制性能。采用MatLab中内嵌的Simulink软件包进行仿真,对积分分离控制器系统进行封装,建立了张力控制系统仿真模型。仿真结果表明,该方法极大地提高了系统的精确度和效率,降低了超调量,达到较高的工程应用价值。
The wrap-up tension system adopts traditional control results in integral calculus backlog of controller, control quantity exceeding the limit, system bigger overshoot, or even a system surge, this is absolutely not allowed in production. Therefore, the integral-separation control algorithm is applied to programming controller to control tension. When compared with conventional control algorithm, it improves control performance effectively. It is simulated by MatLab with built-in Simulink software package. The subsystem package of integral-separation is accomplished and the simulation model of tension control system established. The results of simulation indicated that this method improves the accuracy and efficiency greatly, reduces the overshoot and is highly valued for engineering application.
