Slide 8: Key Applications
KEY APPLICATIONS ©2021 Modelon 8
Slide 9: Example: Motor Control
EXAMPLE: MOTOR CONTROL This example model demonstrates a PID controller that tries to maintain the vane motor at a constant speed. By controlling the air pressure in to the motor the controller can control the speed of the vane motor. A load is model through a brake that is activated at 0.6 s. Pneum
Slide 10: Example: Multi-Position Cylinder
EXAMPLE: MULTI- POSITION CYLINDER This example shows how easy even a complex systems can be modeled with Pneumatics Library. Multi position cylinders typically consist of two or three connected cylinders to reach three or four end positions. There is typically one port for every head- end chamber an
Slide 11: Example: Linear Actuator
EXAMPLE: LINEAR ACTUATOR This example shows the principle of pneumatic stroke cushioning. A typical cylinder drive can very easily be modeled with the cylinder models in the library. ©2021 Modelon 11
