PID控制因为结构简单、稳定性好、可靠性高等优点被广泛应用。针对实际控制系统往往存在非线性因素，常规PID不能满足实际需求，设计了基H1法频响函数估计的变参数PID控制算法。通过对两点激励液压振动试验系统进行随机振动试验，表明H1法变参数PID控制算法对振动台具有良好的控制效果，可以实现高精度的功率谱复现。

PID control strategy with high stability and high reliability is widely used for its simple structure. Conventional PID can’t meet actual demand when the nonlinear factors exit in the control system, then a variable parameter PID control algorithm based on H1 estimator is proposed. A random vibration test is conducted on a two-exciter testing system, and the results show that this algorithm has good effect on the system and can realize high precision power spectrum density (PSD) replication.
