Data fitting with a model
I have performed a system identification on a model (motor with load). The motor with load can be modeled as a fourth order system. The model looks like sys = tf([m2 b k],[m1*m2 b*(m1+m2) k*(m1+m2) 0 0]); Now I want to use matlab to find the optimal values for m1, m2, b, k such that the error between system sys ... 28 Apr 2010 17:26
