This blog is Part 4 of a blog series that demonstrates how the Modelon\u00a0Hydraulics\u00a0Library<\/a> can be used for the model-based development of an Aircraft Hydraulic Actuation System (AHAS). <\/em>In this series, basic steps of the actuation system development workflow will be covered.<\/em><\/p>\n

Previously, Part 2<\/a> and Part 3 focused on the modeling and simulation of electro-hydraulic actuator with datasheet-based parametrization. Part 4 – below – is dedicated to simulating the simplified aileron model in a real-time target.<\/em><\/p>\n\n

The Importance of Real-Time Simulation<\/h4>\n

During the development of a Fly-by-Wire actuator and its control electronics, the trimming of the actuator control laws is of particular importance. While most can be performed with simulation on a standard computer, one relevant step is to include the control laws on a real-time target that controls the physical model (plant model) inputs. These two models are usually not coming from the same software.<\/p>\n

This plant model shall react in real-time \u2013 i.e. the computation of every simulated time step takes less time than the simulated time itself \u2013 to avoid that the model would be delayed compared with real-time orders (this would be a task overrun). This real-time integration enables validating the actuator control laws with more accuracy.<\/p>\n

In this blog post, we will illustrate how the simple actuator model developed in the blog post 2 is integrated in a Speedgoat target and runs real-time.<\/p>\n

Minor Model Adaptations<\/h4>\n

The changes made on the model are the following:<\/p>\n
