thanks for your explanation.yes it is not a school project but I am still in the simulation part in Simulink and the next step is to go for the real time ,so I have just started to explore about Labview,DAQs and how to link with Simulink.
1- I am controlling the stiffness of pneumatic actuator which is a combination between force and position control.
2- My controller is a neuro-fuzzy controller and even I may go for more advance control later which is not supported by labview,that is why I am using Matlab not Labview.(Can I design neuro-fuzzy controller in using labview?)
3- thanks for information about simulation interface toolkit and real time system,I will try to explore more on this.
