I am trying to identify the friction model of the system. There are several model of friction taking the streabeik effect into consideration. suppose i choose any model. for example say Tustin model, how do i find its parameters. Well while capturing the experimental data(for a given force measure velocity), the streabeik effect is there only near zero(very small velocity) region. How do i define this low velocity. At lower velocity(where velocity is obtained by numerical differentiation of position), the signal noise ratio is low. Can you kindly help me out with some suggestion or pointer to some useful literature where i can get more insight into this. kristo
