带模拟位置控制器的液压作动器
此示例展示了如何使用 Foundation 库对跨电气、机械和等温液体域的系统进行建模。在该模型中，在等温液体域中实现的液压系统控制机械负载位置以响应电压参考需求。如果参考需求为零，则液压作动器（和负载）位移为零，如果参考为 +5 伏特，则位移为 100 毫米。

Use the Foundation library to model systems that span electrical, mechanical and isothermal liquid domains.
带数字位置控制器的液压作动器
此示例展示了与在等温液体域中实现的双作用气缸一起在闭环回路中起作用的二通阀。此控制器表示为连续时间传递函数加传输延迟。当以离散时间实现时，延迟允许计算时间（一个离散时间周期）加上零阶保持（半个离散时间周期）。该模型被配置为线性化，以便产生频率响应。要进行配置以实现更快的桌面仿真，请注释直通传输延迟并增加求解器最大步长。
Hydraulic Actuator Configured for HIL Testing
A physical system model and controller configured for HIL testing. It is derived from example Hydraulic Actuator with Digital Position Controller, ssc_isothermal_liquid_actuator_digital_control. The model has been configured for HIL testing by performing the following steps:
混入空气效应
此模型展示了自定义双作用气缸中的混入空气效应。在振荡压力的重复循环过程中，绝对压力不会低于绝对零，因为均质液-气混合物的体积模量在低压下会相应降低。
