求翻译：同时建立了在MATLAB仿真下的液位控制模拟界面和响应模拟曲线，并通过整定PID参数，得出了整定后的仿真曲线和实际曲线。是什么意思？

Establish a level control matlab simulation analog interface and respond to the simulated curves, and by tuning pid parameters obtained tuning the simulation curve and the actual curve.

In addition to establishing a MATLAB emulation of the fluid control analog interface and the response curve, and simulated by the Set PID parameters were obtained after the set of emulation curve and the actual curve.

Simultaneously has established under the MATLAB simulation fluid position control simulation contact surface and the response model curve, and through the installation PID parameter, after has obtained the installation simulation curve and the actual curve.

Also established under the MATLAB simulation of liquid level control of analog interface simulation and response curve, and through tuning PID parameters, came after setting simulation of curves and the actual curve.
