在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。(In process control, according to the ratio of deviation (P), integral (I) and differential (D) to control the PID controller (also known as PID regulators) is the most widely used an automatic controller.)

说明：  包含matlab用到的所有数学计算，希望对大家有所帮助。(Matlab contains all the mathematical calculations used in the hope that all of you to help.)

根据C、M、K矩阵计算模态参数：固有频率、振型向量、阻尼比，并可区分比例阻尼还是非比例阻尼(Calculate the modal parameters C, M, K matrix: natural frequency, mode shape vectors, damping ratio, and can distinguish proportional damping or non-proportional damping)
