考虑幅值谱与相位谱的人造地震动模拟与反应谱拟合 我国对《建筑结构抗震规范》进行了修订，将设计反应谱周期由原来的3秒延长到现在的6秒。反应谱周期的延长。 本程序以新规范反应谱作为目标谱，采用三角级数迭加来模拟地震动加速度(Consider the amplitude spectrum and phase spectrum of the artificial ground motion response spectrum simulation and fitting our anti-seismic construction norms, and the amendment to the design response spectrum cycle from three seconds to extend to the present six seconds. Response spectrum of the extended cycle. This procedure to a new standard response spectrum as the target spectrum, the use of trigonometric series of superposition to simulate ground motion acceleration)

常规PID控制器主要采用模拟PID控制器。这种控制器的控制规律是：根据给定值和输出值构成的偏差按比例、积分和微分通过线性组合构成控制量，对被控对象进行控制。(Conventional PID controller is used mainly analog PID controller. This controller is the control law: according to the given value and output value constitutes a deviation by proportional, integral and differential form by a linear combination of the amount of control, control of the controlled object.)
