摘要
基于对串级控制系统积分饱和的分析,提出了改变PID2和修改PID1闭锁条件2种抗积分饱和方式,并基于Matlab平台对2种方式进行了仿真分析,结果表明修改PID1闭锁条件的抗积分饱和方式既可有效避免串级控制系统PID1的积分饱和,又能保证PID2的快速调节。
On the basis of analysis on integral saturation in cascade control systems,two anti-saturation approaches were put forward,one was modifying the anti-saturation method of the slave controller,and the other was changing the lockout condition of the master controller.Simulation on the two ways above was carried out by Matlab.The result showed that changing the lockout condition of the master controller did not only avoid the saturation of the master controller in cascade control system effectively,but also can ensure the rapid adjustment of the slave controller.
