pid控制

本系统可做自动控制原理中的时域分析仿真实验，系统特性如下： 1：可选择仿真系统为一阶、二阶、任意阶 2：可选择信号源为正弦波、三角波、锯齿波、方波（可模拟阶跃信号），并可调节信号源频率、幅值、相位、偏移、方波占空比 3：可选择信号采样率及采样数 4：自动计算传递函数 5：自动计算时域响应参数（增益系数、上升时间、峰值、峰值时间、稳定时间、超调量） 6：波形图同时显示原始信号和响应信号 注：使用本系统需安装labview控制设计与仿真库(The system can do automatic control theory in the time-domain analysis simulation, the system behaves as follows: 1: simulation system can be selected for the first, second, any order 2: select the signal source is a sine wave, triangle wave, sawtooth, square wave (analog step signal), and can adjust the signal source frequency, amplitude, phase, offset, duty cycle square wave 3: the the optional signal sampling rate and the number of samples 4: automatic calculation of the transfer function 5: Automatic calculation domain response parameters (gain coefficient, rise time, peak, peak time, settling time, overshoot) 6: waveform diagram shows both the original signal and the response signal Note: Use the system to be installed LabVIEW Control Design and Simulation library)
