StateSpaceToTransferFun Routine

Summary

Convert transfer function from state-space to numerator-denominator form.

Declaration

Procedure StateSpaceToTransferFun(num, den: TVec; a: TMtx; b, c: TVec; d: TSample);

Description

:Convert a transfer function defined in state space presentation of the real valued A matrix, B,C vectors and D value in to its numerator Num and denominator Den form. State space system is related to its numerator/denominator representation via the following relation:


               num(s)
       H(s) = -------- = C*(s*I-A)^(-1)*B + D
               den(s)

       dx/dt = Ax + Bu
       y     = Cx + Du

x - input of the system
y - exit of the system
