i have an equation system noted down. my input "y1ref" and "y2ref" comes from a block and with the equations below, the "y1dot" and "y2dot" are calculated. (2 equations are separated and k11,k21,k22 are constant gains) using of derivative made may answers infinite numbers in some points. how can i prevent this from happening(for example how to turn equation to integrator?) i appreciate the help

You require a set of integrator. Your input is ddot(Y2ref) and dot(Y1ref). Use integrator in series to get ddot(Y2ref)->dot(Y2ref)-> Y2ref and dot(Y1ref)->Y1ref. Construct the equation dot(y1) and ddot(y2). Use the integrator in series to get y1, dot(y2) and y2. Use these equations back on the ddot(y2) and dot(y1). This is better than differentiating.
