PID算法简单易行、稳定性好故而在控制领域得到广泛应用,但单输入单输出的特点也限制了其在建筑结构振动控制中的应用。通过使用隔振层位移作为主要控制对象,在分析PID单个环节物理意义基础上,结合Matlab软件,提出一种半经验半理论参数整定方法,并以某集中质量模型为例进行仿真分析,验证了该参数整定法得到的PID控制系统具有十分显著的控制效果。
PID algorithm is widely used in the control field for its simple characteristic and easy to implement. But the characteristic of single input and single output limit its application in building structural vibration control. By using the isolation layer displacement as the main control object,hsed on the physical significance analysis of PID single part, combined with Matlab software,this paper put forward a semi empirical and semi theoretical parameter tuning method. Then using a concentrated mass model as an example to simulate,this paper verified that the PID control system which was tuned by this method has achieved remarkable control effect.
