针对双容水箱大滞后系统，采用PID方法去控制。首先对PID控制中各参数的作用进行分析，采用根轨迹校正、伯德图校正的方法，对系统进行校正。最后采用神经网络PID控制的方法-Large time delay for two-capacity water tank system, using PID method to control. First, the parameters of the PID control in the role of analysis using root locus c

根据宏微系统质量块模型的根轨迹图和伯德图，来研究质量块系统的稳定性问题。通过改变原模型参数值来观察动力学软件模拟仿真结果，最终得到宏微机械臂末端的误差曲线，总结结构参数和物理参数对宏微机械臂系统的影响(the stability of mass block system is studied according to the root locus diagram and Bode graph of the mass block model of macro and micro system. B
