Hydraulic Actuator with Digital Position Controller
This example shows a two-way valve acting in a closed-loop circuit together with a double-acting cylinder implemented in the isothermal liquid domain. The controller is represented as a continuous-time transfer function plus a transport delay. The delay allows for the computational time (one discrete time period) plus the zero-order hold (half a discrete time period) when implemented in discrete time. The model is configured for linearization so that a frequency response can be generated. To configure for faster desktop simulation, comment through the transport delay and increase the solver maximum step size.
