Hydraulic Actuator with Analog Position Controller
How the Foundation library can be used to model systems that span electrical, mechanical and isothermal liquid domains. In the model, a hydraulic system implemented in the isothermal liquid domain controls the mechanical load position in response to a voltage reference demand. If the reference demand is zero, then the hydraulic actuator (and load) displacement is zero, and if the reference is +5 volts, then the displacement is 100 mm.
Hydraulic Actuator with Analog Position Controller and Dashboard Blocks
Use the Foundation library to model systems that span electrical, mechanical and isothermal liquid domains.
Hydraulic Actuator with Digital Position Controller
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.
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:
Auswirkungen von mitgerissener Luft
Dieses Modell zeigt die Auswirkungen von mitgerissener Luft in einem benutzerdefinierten doppeltwirkenden Zylinder. Während des sich wiederholenden Zyklus der Druckoszillation sinkt der absolute Druck nicht unter den absoluten Nullpunkt, da das Volumenmodul des homogenen Flüssigkeits-Gas-Gemischs bei niedrigen Drücken entsprechend abnimmt.
