Hello!
Does anyone help me to convert simple state space model (dx/dt = Ax+Bu) to fixed point form which can be used in DSP (TMS320C24x).
There are some problems: state variables are in the small range (-1..+1), but constants (matrix A) are very big (more than 10000). And if I try to use all of them in the same fixed point format (i.e. 4.12) --- one of them is out of range and another has big sampling error.
